It all depends on the person. Everyone is different. Everyone's priorities are different.
As of now, I don't intend to come out to my family as trigender/pansexual or whatever. Even though my sexuality and gender expression are huge parts of me, they wouldn't understand, and some things are just better left unsaid. I don't mind telling my friends if the subject comes up, though. I choose my friends, but I can't choose my family. I love them and they love me, but I'm not going to pretend that my coming out wouldn't cause a rift between us. Likewise, if they knew I was pro-choice, pro gay marriage, or in an open marriage, they would flip.
