His parents were afghan immigrants. His father is some sort of radical extremist, etc. You let them in, they have kids, raise them to be jihadis, etc and then of course they get to bring in their entire extended families through the madness of chain migration.
We have had three recent terrorist attacks, Boston marathon bombing, San Bernadino shooting and this. All by muslims, all either immigrants or first generation offspring.
When that Root kid shot up a black church, the left immediately amped up its cultural cleansing campaign against any and all artifacts of Southern heritage. Not just Confederate flags, but even schools and streets named for Confederate heroes, monuments to the dead etc.
When it's murderous muslim terrorists however, they walk on eggshells. The Washington Post opined this morning that this was the result of intolerance towards gays, ie blame family values groups, lax gun laws, of course, and our failure to make muslims feel sufficiently accepted.
Their recommendation is to let's be more accepting of muslims and restrict gun rights for law-abiding Americans whose families came over on the Mayflower. Oh yeah, I'm sure they will want to have more and bigger government agencies monitoring us. Just no profiling please.
