Use your common sense.
It's pointless arguing with someone who adopts such extreme skepticism. Should I provide proof that the sun will rise tomorrow, too?
And when I asked the question, I was trying to illustrate a point. You are more likely to want children with a man you are committed to than a man who wants you to act as a surrogate.
i am using my common sense, i suggest you use some logic. and not the logic that's limited to the slot a/tab b kind. logic that suggests that you don't know how sexuality plays out in different social constructs and that we really have no reliable data on whether sexuality is fluid or not and whether homosexuals are in primarily homosexual relationships and what their attitudes are about procreation.
sexuality and reproduction are not convincingly tied unless you're making some really basic, irrelevant argument that homosexual sex itself cannot lead to procreation. you're not accounting for anything beyond that simple fact. i'm suggesting you read up on the social construct of sexuality and decide for yourself.
like i said, my personal choices are just that. they're influenced by my particular socio-economic-gender-race-cultural-sexual background. to try to "prove" a point by relying on what you imagine will be my response is ludicrous.
and i'm done with this. like i said, i really SERIOUSLY have no desire to convince you of anything.
