Something has definitely changed in him, and it has not been for the better.
I listened to Levin for years and years, and he’s always been a bit on the angry side, but I always felt I was learning things from him.
I haven’t though that i have been learning anything from him fora good while now, and on top of that listening to him was making me angry.
I don’t have any need to be made angry, Mark can keep his anger to himself.
I figure you know this, and I don't mean to be preaching to the choir, but just venting out loud. One has to be careful about "learning" from talking heads, all of them, even the ones you like, maybe especially the ones you like. They all make mistakes. Fact checking is a real eye-opener. Tedious, so reserve it for things that are important to your sense of curiosity.
