Personally, I think everyone needs to just stop identifying themselves all together. I feel the labels are where the root of the problem rest. It's all sex, weather it's with the opposite sex or the same. In ancient times, there was no gay, straight, bi, lesbian, ect. It was all "Do you like cock or cunt?" if someone switched between the two, no one cared. Those are the times we need to get back to.
I see it as not much different than political parties. I'm pro-choice and I support tough border laws and ID for welfare. What party do I sign up with? Where as someone else with my convictions would switch one of their beliefs because they feel they have to in order to have an identity or because of pressure from party members. This is why I'm also against political parties.
