Like most people...and I will say this again and again....he was most likely right about some of what he said and wrong about some of it.

I've never yet met anyone who was right about everything.

You can't just say of someone: "He was right." or "He was wrong." You have to look at what they said and realize that like anyone else they were probably partly right and partly wrong. Then go through it all and see if you can learn something from it.

Sheep don't do that. They simply make everything 100% black or white. Everyone is either "right" or "wrong" in the eyes of a sheep, period....and that means no further discussion, no desire to learn anything new, no impulse to understand where another viewpoint is coming from, and no willingness to change.
