Only a psychotic sociopath would project things on to others that they know are false
I don't think you're necessarily psychotic or a sociopath. Lots of reasonably normal people engage in projection from time to time; you could be one of them. As I said, I think you'd do much better, if you put more effort on making a good argument for your beliefs, and spent less time worrying about the mind of the Evil Barbarian.
Think about it.
