"LGBT" is a relic of the fringe counter-culture 1960s, and will be a non-entity in the coming future, so enjoy it while it lasts. I'm sure it will always "exist" in some odd capacity, much like Scientology, or any other idiosyncratic sect that has historically. And I'm sure "homosexual" behavior, will always exist much as it does in less evolved species - but when the minority of disaffected individuals attempting to turn die off, whether early from disease, or evolutionary from non-reproduction it will be extinct as far as culture and society is concerned, as much as disco is.
If individuals who have been brainwashed into the cult and its fictitious "identity" merely to fill some void in a meaningless life wish to escape "persecution" - then leaving the cult and the self-marginalization that it naturally entails, and assimilating into healthy society would be the best option.
I certainly pity any children who've been trapped in such a diseased environment via the ruse of same-sex adoption or in-vitro fertilzation, and hope they have a way out, given the "LGBT" cult's open admiration of NAMBLA and other pro-pedophila organizations, which is well documented by research.
