Never heard of him, though I've been away from Phoenix since January. What station is he on?
I don't think someone is necessarily "nuts" and a "cry baby" and an "idiot" for supporting gun control. They might be misinformed or misled or haven't been shown the facts. Maybe they've weighed the pros and cons of the issue and find our arguments unconvincing. My own wife was antigun when I met her, but has since come around to the point where she carries daily.
Anyway, ad hom attacks (http://en.wikipedia.org/wiki/Ad_hominen) are hardly the way to bring someone around to our side. Calm, reasoned, factual debate is the only way to go.
