 If you don't believe in God, as many if not most liberals don't, if you don't really believe in a moral order, not an objective moral order, maybe you think, I don't know, morals are just something we all came up with. We all, in the early evolution, we all just came up with it to kind of survive. If you don't believe it's real, if you don't believe in an afterlife, if you don't believe in the immortality of the soul, if you don't believe in the reality of things like justice, then why wouldn't you wish death on your enemies?
