I am attracted to either end of the gender spectrum not the middle. I am stupid open minded about gender issues, but I just can't be attracted to the middle ground on it.

To be clear, a person that identifies as third-gendered is very likely NOT in the "middle ground" of any spectrum between male and female; in other words, being third-gendered doesn't always (or even generally) have to do with having some sort of male-female hybrid identity. It very often involves different qualities of identification altogether.

To use a rough (and, admittedly, kind of stupid) example, apples, oranges, and kiwi are all different sorts of fruit, but it doesn't make sense to say that the kiwi is "in the middle" of the apple-orange spectrum. It's just another fruit entirely! Sure, it may have some things in common with apples or oranges, but it's unique enough to constitute its own separate object. And putting so much emphasis on (or framing everything in terms of its relation to) an "apple-orange spectrum" and comparing everything against it ignores the fact that plenty of fruit falls completely outside that narrow spectrum.

I like male and female. Not really the middle ground.

Lets break some thing down here. There indeed are spectrum's, everything is a spectrum, you can sit and tell me how much I shouldn't see things a certain way but the point of the matter is I do, we all do. Lets use race as an example because that works. Obama is considered the first black president, but he isn't black he's mixed. People will associate him as teh race that is predominate in his features. Gender works very much the same way. If you dress act and look like a woman I will consider you to be female, no matter your parts, and vice versa. If you are wearing a skirt have breasts, and leg hair as thick as a shag carpet, it'll gross me out, this is my attraction, what I consider to be masculine and feminine, these opinions are set forth by society of what, the majority of people, in the US consider to be male or female.
Fausto-Sterlling a very famous social psychologist gave us the theory of the Five Sexes, she is also based heavily in Fucco's work on gender but, she was able to simplify the idea and categorize, or give definition to five genders. Many other psychologists and sociologist have identified more genders and can break down these categories even smaller. (( have a link link ))
I am Bi sexual, that literally means attracted to two sexes. If you consider yourself something that is neither male nor female my sexuality does not obligate me to be attracted to you because you consider yourself both gender. You are one completely separate different gender. At best you are Bi gendered, I am attracted to men and women, not bi genders and I don't have to be either. My Bi sexuality isn't a thing people get to mandate, just as I would never mandate your gender.
Since a lot of people like to use Kinsey cause they saw that movie but have no idea what he actually said. The Kinsey scale is what almost ever psychologist and sociologist uses to mark bi sexuality, no where on the scale is ever mentioned, shemales, trans genders, transsexuals, or anything else, Kinsey has other work on that exact subject. The Kinsey Scale specifically covers males and females, nothing in between or outside off. I am Bi I go on that scale, a three if you care to know meaning I am equally attracted to either gender.
That is just arguing the logistics of bisexuality which I could hardly do in a post on Eden that's what research papers are for and vastly smarter people than myself have already done that work for me. I suggest you look up what they have said. Kinsey's writings are a good start. But, lets talk about the rules of attraction, who are you to tell me that I am to just be attracted to you because I am anything? If I was completely strait do I have to be attracted to a woman just because she is a woman? No, if I was gay would I have to be attracted to a man just because he is male? No, and no one would ever say that, so because a person considers themselves both genders and I like both genders I instantly have to be attracted to them because hey two birds one stone right? That's a ignorant and illogical assumptions, I have indeed dated shemales, why because if anyone tried to guess their gender they would have assumed female. I would fuck Buck Angel because as long as he has pants on that is clearly a man. That is what I need to express here, attraction is still attraction. A lot of people thing Ryan Reynolds is sexy, and for some reason I literally can not explain every time I see him I just want to punch his damn face in. My sexuality doesn't determine attraction, it just determines the size of my pool.

In theory, I could have the capacity to be attracted to non-binary and intersex people. That I know of, I haven't met anyone offline in those categories. I think the reason they may be under-represented is that, statistically, there are just a small number of non-binary identifying and intersex individuals.

Another thing is that intersex conditions and how a person identifies can be unnoticeable to invisible. My cis boyfriend could be intersex and I'd never know without a genetic panel and a CAT scan. And if someone only identifies as non-binary but otherwise behaves in a way that is not clearly taboo-breaking, you'd never know either.

To be honest though, I don't really care about the differences between the labels of bisexual, pansexual, and queer. So I may not be the best representation of all bisexuals.

You do have to keep in mind that the term bisexual was coined during a time when non-binary people really weren't acknowledged, even inside the queer community. And even in the queer community now, many people don't know about/acknowledge nonbinaries.

However, I know several people who identify as bisexual who have experienced attraction to nonbinary people. I am nonbinary and id as bi as opposed to pan. I, and other the bi people i know who are attracted to nonbinary people, think of bisexual as essentially meaning "two sexualities", or both homosexual (attracted to the same gender) and heterosexual (attracted to other genders).

Personally, being trans, I'm more leery of pansexual people than bisexual people. It is from pansexual people, after all, that I have heard statements like "I'm pan because I'm attracted to men, women and trans people" (when many trans people are men and women, and not some third gender) and "I don't see gender!" (when my gender is very important to me).

Finally, there's just plain nothing wrong with not being attracted to nonbinary people. Straight people don't have to be attracted to us, gay people don't have to, and bi people don't either.

I like anyone.

While this thread seems to have died a long time ago, for posterity's sake, I'd like to make myself perfectly clear on two points:

(1) The fact that "bisexuality" includes the prefix "bi-" does not automatically end the discussion of whether bisexuality includes attraction to more than two genders of persons. The "bi-" can still be read in two different ways: (a) two GENDERS (in which case it follows that bisexuality entails potential attraction to only two genders of persons) or (b) two biological SEXES (in which case it follows that bisexuality entails potential attraction to effectively all persons, since most all humans are either XX or XY, and therefore, to more than two genders).

(2) When I say that something rubs me (emphasis on "me") the wrong way about a bisexuality that leaves out third-gender folks, I'm not saying that I think anyone is bad or wrong for not being potentially attracted to third-gender folks. You're bisexual and not attracted to third-gender persons? Great! The fact that YOU identify that way doesn't "rub me the wrong way" or bother me at all. It's only the idea of ME identifying that way that I don't like (which, conveniently enough, is why I identify as inclusively bisexual).

I find people attractive who make me feel comfortable and make me laugh. That's what matters to me.
