If you wanted to continue that discussion with him, you could say that he dodged the question, and put up a bizarre strawman that had nothing to do with the question of survival as a species.
You might also point out a second strawman argument which he's used. That of, surely it's a human right to love whomever and however we please. Really? This is a pretty brand new "Human Right," just created (or discovered) in the last 40 years. You might remind him that the OP was not talking about human rights, but about more fundamental issues such as survival of the species and the creation of man.
Of course, you don't have to use any of those thoughts. Up to you.
