You will laugh. It sounds like my dad. Instead of taking my gay lifestyle seriously, he makes it a joke. Saying inappropriate things a lot of the times. It's just his way of dealing with it, I think. I usually don't bother with getting angry, because in all honesty, it's better than condemning me for it. Maybe in time, he'll realize how ignorant he was and apologize. But then again, maybe not. Don't let it get you in a huff. I'm sure he still loves you. :)
