It's not "giving up" heterosexual relationships / children. It is really, really odd that heterosexual people immediately think that their way of life will be eradicated because LGBT folk are getting more options to have happy lives. Do you think that, given the option to have a relationship with an individual of the same gender, that all heterosexual people will suddenly be unwillingly seduced into homosexuality? If so, might want to examine those feelings with a qualified professional.

For some reason, “traditionalists” seem, implicitly from their arguments, to think that traditional heterosexual relationships are a horrible torture that no one (or perhaps just no one on a particular side of the asymmetrical relationship) would bear if they weren't the only option fully sanctioned by society.

neurobiology is more involved than that, you'd be surprised :)
