It's not like people just choose their sexuality based on what they see around them. Otherwise we'd never have any gay people arising from male/female parents. If a boy isn't gay, seeing that he has 2 dads is not going to make him more attracted to males. Although, according to Kinsey, we're all a little gay anyway - so seeing it as a socially accepted thing might make kids willing to experiment more. But it wont make heterosexual people suddenly become homosexual. Just as having heterosexual parents doesn't turn gay people straight.
Hell, lots of gay kids have to cope with insane amounts of resistance from their parents/society over their sexuality. Some even get sent to boot camps specifically designed to "make them straight again". Yet it never works, and has been openly acknowledged as harmful. I'd like to think that homosexual parents would be accepting of whatever sexuality their kid happened to be. They at least know pressuring them does nothing.
Oh, and
women produce testosterone too. Masculinity is a socially accepted definition, not producing a hormone or a having a penis.
Edited to add: Oh and to answer the question. Homosexuals are just as capable as heterosexuals at raising kids. No-one blinks an eye at people living below the poverty line having children. Noone cares when someone without a highschool education pops one out. Why draw the line at a particular
sexuality of all things.
