Your friend's friend was trying to get a rise out of you. I've gotten to where I respond the same way. They can believe it or not at this point. I no longer try to wake folks up anymore and refuse to argue with the norms, I will discuss politics with like minded frens only. If people see what's happening, they do. If not, oh well.
I think you handled it great, it's never worth the effort and always leave them with something to ponder.
I refuse to argue with liberals, it's like arguing with a blind person about the color of grass. Until they see it for themselves, the argument is futile. I don't even try to wake people up anymore, if someone refuses to wake up, it's on them at this point. They can't say I didn't try.
