Did “political correctness” allow Maj. Nidal Malik Hasan to escape detection and allegedly kill 13 people? Some conservative commentators and politicians are claiming that.
Arizona Sen. John McCain has already done what the military is urging Americans not to do , "speculate" about the motive in the Fort Hood killings. Calling the killings “an act of terror,” he said, “this may sound a little harsh but we ought to make sure that political correctness will never impede national security.”
McCain is expressing concern about allegations that Hasan's superiors played down his extremist views because they didn't want to alienate a Muslim soldier. McCain is not alone. Conservative columnist Ann Coulter said on Baltimore's WBAL radio, “It's just I think the constant increasing menace of liberalism ... we're certainly getting it from the commander-in-chief.”
In reference to Gen. George Casey, Coulter said, “It’s pretty shocking ... and here I thought they didn't allow gays in the military ... shocking!”
Others, like Democratic Representative Joe Sestak, a former Navy admiral, dispute that view. Sestak insists the military should be diverse and its leaders sensitive to minority soldiers. He said critics like Coulter are doing soldiers a disservice, at least until all the facts of the case are known.
Watch: Is our military too 'P.C.'? 
“If there’s anything they should be advancing, it’s, wow, think about the stress they’ve gone under,” Sestak said. “That’s what we should be highlighting. Not going off into right or left field, until we know."
The U.S. Marine Corps rejects the notion Muslim extremists are hiding in its ranks for any reason. First Lt. Josh Diddams told CNN the Corps, “has not seen any trends that indicate individuals are any more ... likely to be involved in an incident based upon their religion."
A look at history seems to bear that out. In March 2003, Sgt. Hasan Akbar, a Muslim, killed two fellow officers in Kuwait and court documents indicated religion was a factor. But there are many instances of solider-on-soldier killings where religion is not considered a factor.
In May 2009 Sgt. John Russell allegedly killed five fellow soldiers. In 2004, Senior Airman Andrew Witt killed a fellow airman and his wife. In 1995, Sgt Will Kreutzer killed one soldier and wounded 18 at Fort Bragg. Those incidents weren't seen by our country's leaders as potential impediments to our national security although some say they should have been.
What do you think? Is our military too 'P.C.'?
