Well, Kind Of.
The only people who know I'm bi are my college friends. I'm pretty open about it on campus, since people up there are generally cool with that sort of thing.
Home is a different story. My dad is the kind of person who makes people hate the Republican party. He's pretty open about the fact that he thinks that homosexuals are the scum of the earth and that sort of filth isn't allowed in our household. (For example, a good friend of mine in high school was a lesbian. My parents forbade me to do anything with her outside of school--they couldn't prevent that.)
So, it's pretty much a given that I'm going to get kicked out if I come out. I'm closeted to my parents out of necessity. I simply don't have the means to support myself right now: I'm still in school, and my degree program keeps me busy enough that I don't have time to work on the side, while still keeping the grades to keep my scholarships. As much as it depresses me that I have to hide such a large part of myself during the few chunks of the year I'm living at home, it simply isn't practical right now to come out.
I've thought about telling my sister, though. We're really close and I've had the nagging suspicion for a while now that she's a full-out lesbian. And my mom has a cousin who I suspect would be really supportive of this sort of thing. But my parents? I'll probably hold off on telling them that I like girls until I'm established as financially independent. Besides, I really don't plan on staying close with them. Sure, they are my parents; they gave birth to me and raised me and everything, but I can't bring myself to fully love and respect a pair of people who can't bring themselves to accept me.
