Hardly 'my phrase', it is a simple fact of science, and you have no logical reasoned response. Denial simply exposes your fear.<quoted text>
Again with your new phrases. So silly. Now, all you have to do is prove that gay couples legally marrying will cause straight people to mate irresponsibly.

Good luck with those.
As to procreation, you are confusing a fruit tree that does not produce fruit, with a nut tree that does not produce nuts but wants to be a fruit tree.
