Was it not just eight months ago, after Tuscon, people on the Left decried “eliminationist rhetoric” and the military technology common in many political campaigns?
It was. So where are those New York Times columnists today?
There is a double standard in the silence from the Left about an online video game called “Tea Party Zombies Must Die”, featuring prominent Tea Party members such as Sarah Palin, Mike Huckabee, Newt Gingrich, Michele Bachmann and even the Koch Brothers. The gamer is instructed to kill each Tea Party member with weapons like a gun or a crossbar.   In January, Paul Krugman opined, “It’s true that the shooter in Arizona appears to have been mentally troubled. But that doesn’t mean that his act can or should be treated as an isolated event, having nothing to do with the national climate.” 
US Rep. Andre Carson (D-IN) said Tea Party Members of Congress want to see blacks lynched and “hanging on a tree”.  Let us refresh ourselves of the January words of Paul Krugman: “Where’s that toxic rhetoric coming from? Let’s not make a false pretense of balance: it’s coming, overwhelmingly, from the right. It’s hard to imagine a Democratic member of Congress urging constituents to be “armed and dangerous” without being ostracized”  The Times’ Matt Bai wrote, “the problem would seem to rest with the political leaders who pander to the margins of the margins, employing whatever words seem likely to win them contributions or TV time, with little regard for the consequences. ” 
I provided many other recent examples of uncivil Left-wing rhetoric in my recent post: https://econscius.wordpress.com/2011/08/03/giffords-the-era-of-civility-bidens-terrorists/.
President Obama just attended a Labor Day rally where James Hoffa, head of the Teamsters Union, said:
“We’ve got to keep an eye on the battle that we face — a war on workers. And you see it everywhere. It is the tea party. And there’s only one way to beat and win that war — the one thing about working people is, we like a good fight.”
“President Obama, this is your army, we are ready to march. But everybody here’s got to vote. If we go back, and keep the eye on the prize, let’s take these son-of-a-bitches out.”
