said, you can be wrong. People will forgive you for being wrong.
But they will never forgive you for being right and contradicting their cherished beliefs. And THAT, ladies and gentlemen, is why Lefties hate you and refuse to talk with you. And arguing with you is just pouring salt in a wound for them. So they simply won’t do it. You are a walking repudiation of their cherished beliefs.
But they can’t stand that. So you have to be summarily dismissed, so they don’t have to defend their beliefs.
And it is perfidy–a betrayal; a deliberate breach of faith.
