Society doesn't specially nurture anything.

Oh, ok. Society is an amorphous nihilistic chaos, with no norms or mores, promoting nothing in particular. My mistake.

Saying that society specially nurtures heterosexuals is like saying that it specially nurtures people who have all their limbs.
Society doesn't go out of its way, so to speak, to give groups an advantage. Individuals may, and certain groups might, but not "society" as we normally define it, imho.
