Being gay might be genetic, but what about the flamers that basically run around acting like complete morons during gay pride parades? To me, they do more harm than good to the lifestyle. When someone says they are gay, is the first thing that pops into your head two "normal" looking guys in a relationship? No, it's the Village People Jello Orgy Gone Wild crowd that you think of.
Personally, I completely disagree with the gay lifestyle, but I do believe that each person is entitled to live their life how they please. This is an arguement/discussion that's gone around in circles thousands of times before, and will probably continue to do so, but since I don't feel I should push heterosexuality on someone who is gay, then why should I have it pushed on me to accept it?
