Lets all think here for a bit: Why are homosexuals a 'minority', whereas redhaired, or lefthanded, or tall or short people are just... people with some less common atribute?
Its because we make a big fakkin deal out of it, even where it realy is not relevant.
Its human nature to group others and themselves. To make easy little categories of people and judge them by whatever standards that entails. This is a nasty, shitty habbit that has been and is one of the majour causes of misery on all scales.
This convention, I am sure everyone will have a great time, having a safe haven does feel good, but it does not solve the problem.
Your preaching to the choir, sitting around the table to discuss your problem with only the people that agree with you (yes anyone is welcome, no homophobes wont be there).
Discuss the problem with and amongst people that disagree with you. Convince people that actualy need convincing. Stop labeling yourselves with increasingly silly sounding words. Maybe one day your sexual orientation will be seen as just another atribute of you, rather than you sole defining feature.
Ancient greek society hated just about everyone and everything except homosexuals so its got to be possible.
