Ask as Jesus did...
"Who are you to judge.....?"

Sometimes the absurdity of peoples ignorance can't help but give you a giggle or two. I just normally smile and say pray for me . The sarcasm is lost on them, but sure makes my day.

I think your final sentence should have stopped after the word "think".

If it helps, I like to keep Trump supporters in my FB friends lists. Not because I or they actually agree on politics but simply because I find it entertaining to find out what people in the "other camp" are saying.

laughter can derail a serious potentially thought-provoking discussion, but there's no persuading someone stuck on their own views (like the Christian lady who tried to convince me that I had to take all of the stories about Jesus in the bible literally)
