While the media has remained obsessed with the trial of George Zimmerman, they systematically ignored the stories of three other men simultaneously being brought to justice.

In a courtroom in Boston, the Islamic radical who set off lethal bombs at the Boston Marathon was being arraigned.

At Fort Hood Army Base in Killeen, Texas, another Islamic extremist, Major Nadal Hassan -- trained as a psychiatrist, promoted, paid and armed, all with our tax dollars -- is on trial for mass murder.

And in Cleveland, Ariel Castro has pleaded not guilty to hundreds of charges of rape over a period of 10 years. His trial may yet turn into a media circus, particularly if it affords the Fourth Estate the opportunity to ignore the uncomfortable facts coming out about the Islamic extremists in Boston and at Fort Hood.

The shooting of Trayvon Martin by George Zimmerman captured the fascination of the press. It also highlighted the ridiculous extremes to which the political left will go to perpetuate an agenda of racial division in a nation that has clearly moved on from our admittedly disgraceful past.

Barack Obama and Eric Holder's useful idiots and race pimps -- Jackson, Sharpton, et al -- have attempted to draw parallels to the historic, racially motivated murders of Emmett Till, Medgar Evers and Martin Luther King.

Really? Is this what race relations in America have come to -- comparing an aggressive teen with a chip on his shoulder that got him into a situation that caused his death with the cold-blooded murders of three black victims half a century ago?

Emmett Till was a 14-year-old boy from Chicago who was visiting relatives in Mississippi where he was kidnapped, beaten and had one of his eyes gouged out before being shot in the head -- all for the crime of speaking to a white woman. That was 1955.

Medgar Evers was a civil rights leader who died in his driveway in Jackson, Mississippi, in front of his wife and children, after being shot in the back with a rifle. That was 1963.

And, as we all know, Martin Luther King was shot in the neck while standing on the balcony of his motel in Memphis, Tennessee. That was 1968.

Do those who would equate these terrible crimes with what happened to Trayvon Martin in 2012 really believe that we have not moved forward?

Can you race peddlers living in the Jim Crow deep south of the 1950s please finally, finally get over yourselves?
