Why don't we kill pedos?

Why don't we kill pedophiles and child molesters? I see these freaks bragging about being pedos or talking about kids they see in public all the time here on 4chan. Execute a few thousands of those sick shits and I fucking guarantee that shit will stop.

pedos are terrible parasites, but gays are the most evil fuckups on earth. They need to be hanged from light poles until people get the message that that shot is not okay, not even top think about. It's disgusting.
