Oh, I used to not understand bisexuals. I figured it was just a phase, kind of a last desperate grasping for the heterosexual normality you'd be leaving behind (I was wildly projecting my own insecurities). Then I met a completely confident, completely self-assured bisexual man. He'd been bisexual his whole adult life, was with a man, broke up, fell in love with and married a woman. He and I talked quite a bit, and he disabused me of some of my notions. He also got my respect. He had the option of distancing himself from the gay community and the problems we face in daily life. He could have disappeared into the anonymity of the crowd and let us fight on our own. He didn't. Unfortunately, like you, he didn't always get a warm reception, but he still stood his ground.
