I know exactly what you are talking about with beck and Levin,with Levin however I know he was Rush's lawyer. I owe a lot to Rush's wisdom about radio and other stuff,so I get Levin also he has a NYC personna which takes a bit of getting used to. I think Levin is OK.He's a bit judgmental but comes up with spikes of wisdom from time to time.
Anyway I am at the point where if any of them spout off good stuff about conservatism I listen. When the don't I turn them off.
If I didn't and waited for the perfect there would not be much to listen to. You are a really smart guy,if you wait for the equivalent on the air you will be disappointed often.
