A while back I was on FB arguing with a liberal friend against abortion of any kind and I had a Internet-Rando pop in and say he wished my daughter (who was 3 at the time) would be raped and impregnated so I'd understand the value of abortions.
I screen shot it and went through his friends list and sent it to them. Including his grandmother. Also went through his public pictures and posted copies there as well until he blocked me. Joke was on him though, I took screen shots of his friends list and kept sending it to them all.
You ought to do the same to those people who think this is funny.
