More verbal shots were being fired by talk-show commentators at one another in the clash over gun control on Thursday. On his radio show, Rush Limbaugh laid into CBS's Bob Schieffer for his remarks chastising President Obama for timidity in taking on the NRA. Surely, finding Osama bin Laden, surely passing civil rights legislation -- as Lyndon Johnson was able to do -- and, before that, surely defeating the Nazis was a much more formidable task than taking on the gun lobby, Schieffer had said following Obama's speech outlining his gun-control plans. Why is that not an example of just over-the-top defamation, exaggeration, insulting, not to mention a lack of civility? Limbaugh asked. Where is the media outrage at Bob Schieffer? But Schieffer found support for his remarks from former NBC anchor Tom Brokaw, who compared the lack of public support for gun-control measures to the lack of support for civil rights legislation during the 1960s. There was a lot of silence at the time. Now it's time for the people who do have strong feelings, who are feeling that they can't do anything about it, to kind of band together and have something to say [about gun control]. But on Fox Business News, Breitbart Editor at Large Ben Shapiro described President Obama's remarks as nonsense and accused the president of preach[ing] from atop the graves in Newtown. However, conservative MSNBC host Joe Scarborough, a former Republican Congressman, insisted that Republicans opposing all gun-control proposals are on the wrong side of history, fighting for survivalists who need assault weapons instead of fighting for lower corporate tax rates to make our country more competitive across the nation.
