What's the difference? I really don't care how many there are. If fact, if the only thing 'they' have in common is the desire to have sex with people of the same sex, it's is not much of a political movement. That is why the political forces behind them so wildly distort the degree of and even the very difinition of discrimination. They are looking to unify these people as victims and attract the knee jerk bleeding heart contigent to join in. Other than that, there is nothing besides 'kinky sex' that distinguishes them as a group. Not much to hang your hat on there.
