That may well be, but sometimes the masquerade is a bit too obvious. I haven't heard his radio show, and have only heard him on radio as a sub for Rush. I've seen the same brash ideologue on occasion there, and even though I agree with most of his views, it's an irritant. He's not offensive to me all (or even most) of the time, but it's often enough to keep me from being a regular viewer of his show.
Agree with you about Sammon.
