In case you still think you can convince the Left through persuasion, facts, reason and arguments, watch this brief video of Turning Point USA's Charlie Kirk trying to have a civil conversation with some screaming women.
Notice that they shout him down, hold signs in front of his face, interrupt him and are generally rude and uncivil. He is trying to politely answer questions but they don't care what he is saying. They are just infuriated that he dares to say something they disagree with. I don't think they are mad at what he is saying, they are just mad that he is speaking.
They don't care about facts.
They don't care about the rule of law.
They don't care about reason.
They openly reject civil debate.
Stop thinking that the problem is that we aren't getting our message out. The problem is that we are trying to debate political philosophy with a violent fundamentalist religion. If you have ever tried to have a reasonable conversation with a KJV-Only type, you know what I am talking about. Now multiply that times a million and instead of being some obscure Baptist church now you are dealing with millions of people itching for an excuse to get violent.
That is what we are dealing with.
