Unbelievable. I don't care. I don't believe it matters much in who they are as individuals. You do.
You think this is part of their nature as homosexuals? Or are you just making some bigoted generalization.
Unless you can show me that they are hardwired in some way to be emotionally unstable and promiscuous then your "tendencies" are not necessarily true of the individual even if they are true of the group (which you have not shown).
I don't judge individuals based on the tendencies of their demographic group. That's just a form of collectivism.
For instance, I don't assume you go around looking for Jesus or the Virgin Mary in odd places (e.g., a piece of toast) even if that does seem to be a tendency of Catholics.
