How does one define homophobia when I don't think people know what "homosexual" means. I don't think homosexual people know what "homosexual" means.
Are men and women in prison "homosexual" who are arguably straight heterosexual, and may never have had a homosexual thought/fantasy in their life, then have homosexual sex in prison, then go back to being exclusively heterosexual once released, and may never have had any homosexual tendencies if they never had been incarcerated?
I think there are people who definitely didn't "choose" to be homosexual, clues were there from early childhood from the time they could walk, talk, or play. However, I think it's naive to think there aren't people who did "choose" it, or life circumstances did lead them in that direction.
Then what about cases that might be gender identity problems. Is a woman who feels/believes herself to be a man, and as such has relationships with women, really a "lesbian"?
Are effeminate homosexuals even the "same" kind of homosexual as butch homosexuals?
Ultimately, there are obviously plenty of people who are pretty stereotypically gay or straight, it's like the concept of race, lots of gray areas, but "you know it when you see it" etc. However, there are LOTS of people who don't fit into the neat classifications either.
Are you homophobic when presented with the "idea" of homosexuality, like say some rural fundamentalist Christian might be expected to react?
Are you only homophobic when they hook you up to body monitors that monitor for stress symptoms, then put you in a room with homosexual people, and they record sufficient results?
Are you still homophobic when you only react in a room full of leather daddies and drag queens, and butch lesbian bikers, but don't react when it's a room of people in business suits having a business lunch that you're told are homosexual?
What if there are homosexual people who freak out around the extreme examples of their "culture"? Are they homophobic too?
