My entire identity isn't defined by my being bisexual. Just my attraction to both sexes, that's what's being defined. If you met me in the street you wouldn't know I was bisexual. Just so you know that your sweeping statements aren't actually accurate.
Also, just so you know, gay pride parades where people act blatantly different are places where people act blatantly different for a reason. Because people, people like you, see them as deviants if they reveal themselves to be part of the LGBT community, and treat them as such. That's bullshit, that's absurd, that's psychologically harmful and that's what makes people flaunt their sexuality in gay pride parades (for the most part). To show people like you that they are different from you, in the most obvious way possible and that they don't see that as a bad thing and know you've no genuine excuses for doing so. Do you honestly think most homosexuals walk around without a shirt, or in underpants, or covered in glitter? They're doing that to say "yes, we are different to you. No, that does not give you the right to belittle us. Look at this and deal with it." You do not have the moral high ground here. You cannot try and force someone who is homosexual to conform and pretend they're not, just because you think it's inappropriate without any real excuse for doing so. What you need to do is understand that homosexuals expressing their homosexuality is not a threat to you, is not going to destroy the military and you need to treat people as people, not as homosexuals or straight men, and you cannot just claim that you will if only they agree to act straight around you, because that's a ridiculous request.
The important thing to remember is the LGBT community is a culture specifically because it's not accepted as mainstream. Specifically because people like you force it to be so. In Melbourne, the designated 'gay neighborhood' in town is actually starting to shrink and dwindle, specifically because people are more accepting and tolerant of LGBT's. If there wasn't such obscene prejudice towards it, prejudice that you yourself are perpetuating, people wouldn't need to build such an identity around being homosexual.
