What would be the evolutionary reason for gayness/lesbianism to exist or is it purely a malfunction?

    Not everything which is genetically determined has a function and sexuality is probably not primarily genetically determined. However, for technological species such as ourselves, there's no evolutionary reason for heterosexuality either. We could just reproduce by aritificial insemination if we chose to do so. That said, it's been suggested that loving couples provide a backup adoptive parenthood for orphans.

    Being LGBT is a congenital condition. (developed before birth) Science is finding more evidence for it, every day. Therefore, it is not a sin, which is an outmoded concept.

    There are 1500 animals, birds, and insects that choose same sex partners. How is this a malfunction? We are just like other animals in nature.

    Perhaps it's just some kind of mutation

    Since our finest minds can't seem to sort out whether the appendix serves any purpose or not, I don't think a poll on Y!A is going to shine much light on the role in all species that homosexuality plays.

    This is but a troll's simple-minded idea of how to suggest homosexuality is sin.  Enjoy.

    Not every evolutionary change has a 'reason', but if there were one it might have to do with the planet being horribly overpopulated.

    Gay men are good uncles and have more time for their nieces and nephews.

    I don't believe there is any significant evolutionary advantage. That is just retrospective rationalization.

    It's a choice of style of living, not evolutionary function.

    Any evolutionary reason given will be ex-post facto and hence require a god to have intervened to give reason to it. It's crazy how people say things like "seeing is beneficial to not seeing, thus eyes were evolved" or "Some parents abandon their young thus gay parents evolved"

    Homosexuality has no evolutionary advantage, it just happens.
