CNN's Piers Morgan has been on a rabid anti-gun rant since July's Aurora, Colorado, shootings that has gotten even more venomous after Friday's massacre at Sandy Hook Elementary School in Connecticut.

On Tuesday, he rudely and disgracefully tore into guest Larry Pratt, the Executive Director of Gun Owners of America, calling him "an unbelievably stupid man" who's "dangerous," concluding the interview by saying, "You shame your country" (video follows with transcript and commentary):

PIERS MORGAN, HOST: The AR-15, as we've now seen from the last three mass shootings in America, Aurora, the shopping mall in Oregon, and now at Sandy Hook school, is the preferred choice of weapon for disturbed young men who want to commit mass atrocity, can fire hundreds of bullets at rapid speed, if you have the right magazines.

The president of the United States has indicated he wants to ban assault weapons like this. What is your view?
