Holy crap. Okay, Heather, this is the point where you have to decide what your goal is here. That reply is filled with so many fallacies there is basically nowhere to begin. And it’s given with such a know-it-all condescending tone, I can pretty much guarantee there is almost no way you’re ever going to make headway with this guy.
So you need to figure out what it is you want from this discussion with him. Convincing him of anything, or “setting him straight” or getting him to admit you’re right about something are certainly not options. The best you could hope for is educating him about something, but even then he’d never concede a single point, let alone admit he learned something from you. This guy would rather maintain a point he knows is wrong rather than be proven ignorant or misinformed.
At this point I can tell you the only possible reason for continuing with this guy is for simple enjoyment of the debate. If you get enough utility out of it, and it is more than enough to compensate for having to put up with his nonsense and his attitude, then by all means, go for it. If you need help we can offer pointers and answer questions.
But if you’re just interested in educating people, you’ll be much better off moving on to better fruit.
