If it's self-obvious now, then it always was, making your "high school biology class" comment at #250 kinda pointless.
You are aware that you were making a counterargument to what was just an ironic observation on my part?
What exactly does that mean? I took it to mean that it is somehow astonishing that homosexuals originate from a male-female union. I don't recall anyone ever claiming otherwise. Regardless, it seems to be a rather unusual statement, so I commented upon. If I am in error, perhaps you could clarify.
