I think it’s a matter of projection. When leftists disagree with someone, they want them dead. They assume that conservatives think the same way.
Charles Krauthammer out it this way: Conservatives think Progressives are stupid, Progressives think Conservatives are evil.
Exactly. Leftists can't understand the concept of living peacefully with those that they disagree with. Their brains can't even process it. It's also what makes conservatives such push-overs. They don't understand that leftists really wouldn't care if they were all dead. They think leftists are just a bit dramatic. NO, STUPID REPUBLICANS! LEFTISTS WANT YOU DEAD!!! HOW CAN YOU NOT GET THAT?
