First off, Alex Jones can't be compared to your average gun owner. He is a conspiracy theorist nut job, and does not represent the bulk of gun owners in America.
Secondly, why do you think they invited Alex Jones on the show? Because they knew he would go ballistic, as he always does. Funny you don't mention other interviews that have taken place, where the pro-gun guests have remained calm and rational in their arguments, while the host goes ballistic.
Like this one, where he interviews Larry Pratt and Piers Morgan calls Larry Pratt an "Unbelievably stupid man"

Or this one where Joshua Boston remains calm and rational.

Or this one, again, where the guest presents calm, rational arguments

And therein lies your, and every other anti-gun lobbyist's, problem. They never seem to quote the interviews or articles where the guess presents calm, rational facts even though the host is attempting to incite an emotional response.
