There you go - and that is why gay marriage is shouldn't be recognized by the state - it does nothing for the state, whereas heterosexual marriage does.
Exactly. Not one single taxpayer/citizen/"human resource" has ever come out of the physical coupling of two persons of the same gender. Not one. Whereas ALL the taxpayers/citizens/"human resources" that the state has have come out of the union of a male sperm cell and a female egg cell. And the best way to get these cells together is still the normal, heterosexual sex act. (Unless one wants to make babies in laboratories, as in an Orwellian nightmare world. Even in the Orwellian nightmare world, though, they still need one MAN, to get the sperm, and one WOMAN, to get the egg.)
Homosexuals can't get along without us. Without heterosexual sex acts, there wouldn't be any children for them to adopt when they get to middle age and suddenly decide that they want to play "family". Where, I wonder, is their gratitude to us? For that matter, where is their gratitude to their own parents, who were "backward" enough to engage in normal, procreative sex?
