Kanye is bipolar; so, yeah, I suppose you can call him crazy. So are many other performers. I guess that makes throwing around the crazy word o.k.
As for Carlson, I’m not aware of any mental conditions. But, since throwing around the crazy word is o.k., why not?
Remember, the other side can engage in hate, name-calling, incitement of violence, and engage in violence because, you know, they are - according to them - the good people. We, on the other hand, are - according to them - the bad people.
I also think Kanye enjoys being a contrarian.
