Civilty is one thing (I don't much mind people being uncivil), but anti-government & anti-liberal hate speech on the airways may be dangerous. You know, the stuff that paints government & liberals as actual enemies of America. Since the Vietnam War days, its been the right-wingers doing all the killing - none from the lefties. None.
Just last year Beck put the liberal Tides Foundation on the map when he declared it an enemy of America, then a Beck follower drove up to SF to kill liberals. He died in a shootout with police before he could kill them (did shoot some cops).
2009 - Ultra-rightie Mahon sent a mail bomb to the diversity office in Scottsdale.

2009 - The day after Obama's inauguration, ultra-rightie Keith Luke shoots a buncha blacks & kills two in Mass.

There's like 30 other incidents going back to year 2000, but (not counting McVay's 168 victims) most of the actual right-wing killings took place in Obama time.
