"Homosexuality is a choice" and its paradox

[Esquilax]

I think you could argue that the privilege of accepting your parents' investment in you (i.e. by making you) gives you some moral obligation to match that investment with one of your own. Hearing, "Ewww girls are icky" isn't very encouraging for parents hoping for grandchildren.

Hmm... flawed on several counts. For one, nobody has an obligation to repay a debt they never consented to incur. And even if we were to accept this, who says my parents would want payment in the form of grandchildren?

More than that, how does this even relate to the marriage issue? Plenty of married couples go childless, either through choice or otherwise, and nobody is prodding them with this moral obligation of theirs.

And hey, it's not like the foster system isn't overflowing with children in need of good, permanent homes; those grandchildren aren't so impossible afterwards. Surrogacy is also an option.
