Why am I insulting LGBT guys/gals? Everybody is free to choose, but it is still a fact that reproduction (or rather, having kids) is important for a lot of people. Even some LGBT people try to adopt children afaik.
I know that, I was being sarcastic towards the attitude that sees things that formed the bases of society since ever was one, like reproduction, are viewed as "optional" or "sexist" nowadays, because we should be "above that".
Of course we only get to have the privilege of saving that (and still have a human population on the planet) due to overpopulation in other parts of the world, and we still get declining and aging population our own countries for that.
That's also why we get to have our LGBT privilege. In the large scheme of things, a mostly LGBT society would mean a dead society, because of no reproduction.
But LG cannot by definition, except if they momentarily act like non LG's by reproducing with other partners against their own sexual preferences.
And that if they _do_ have the will to reproduce, considering that in primates in nature it's a strictly heterosexual deal (and in fact, the male/female sexes were evolved as a means to that very end).
In addition, for several prominent LG thinkers, "gay marriage" and "having a baby" (surrogates, etc), is the losing proposition of adopting/mimicking the dominant paradigm. Essentially it's the opposite of feminism.
I can see this happening in nature if maybe both of the original parents got killed off or something. The presence of homo-penguins means that the offspring might get rescued and safely reared by the happy couple instead of perishing.
Also without reproduction nobody would be here.
