The problem isn't really out in the open harassment anymore though. I haven't been in HS for a bit now, but I'm a grad student in a fairly progressive university. Nobody would really think we have homophobes here anymore. But, in reality they exist and just learned how to hide it better.
To give an anecdote, I'm quite straight passing and it came up that I had a boyfriend at a bar with some other students while at a conference. For the rest of the week, this one guy in my cohort would make comments to me once everybody else got out of earshot. Stuff like how "sneaky" I am or how he wondered why they let people like me into the conference. I just ignored him and it eventually stopped.
Are you gay? Because, if you're not, then you might just not be experiencing the homophobia head on any longer since it isn't so much out in the open.
