I think there is a time and a place for a bit of bombast. I think even Alex Jones' appearance on Piers Morgan's show ended up being a net positive because people are moved when they recognize passion. They aren't moved by dry, even toned recitations that sound like a member of the school debate club arguing for an assigned position -- one that they may not even personally hold -- just because it's good academic exercise.
The conventional wisdom is that you have to be emotionless and strictly factual, and absolutely do not make it personal. The way I see it, we've been pretty well having our asses handed to us in the Culture War by strict adherence to this mindset. If it were anything like a fair arena of ideas then I would agree with this idealistic view. But we know it's anything but a fair playing field, and our only avenue for success is to bypass the media's filter. And that means that someone like Alex Jones might have to take advantage of a live broadcast and totally upend their planned formula. I note that no other outlets have had him come in for an interview, and I find that rather telling. If they really thought they could lampoon this caricature of a right wing loon, and by extension paint all gun owners with that brush, wouldn't they be doing so? They live for such opportunities. I think it's an implicit admission that they don't like it when we get angry and in their faces because it causes their information filters to breakdown.
