Interesting, I generally think of hatred as a very draining feeling that I can only feel for so long before I just want to let it go.

The thing that makes it seem particularly difficult to me would be the large amount of people that includes. Maybe where you live there aren't that many pro-lifers or something, but it's about fifty percent where I live. Do you, like, ask everyone you meet what their position on abortion is so you know whether you hate them or not? If not, what happens when you become friends with someone and then find out they're pro-life? Do you just break off that friendship and never talk to them again?
