Anyone that didn't think in the back of their mind "I bet it was a Muslim" is lying or lacking in imagination.While some might want to spin that as a sign of pervasive racism/xenophobia... it's actually just a healthy dose of common sense.It's not politically correct... it's just reality.To balance the point, I generally assume all serial killers are white guys... because most of them are white guys. I assume most rapists are men... and I assume most school shootings are done by loser outcast kids...Are you afraid an old lady will mug you... or six twentysomething guys at 2 in the morning? The same part of the brain that answers that question makes the assumption above.Just an obvious point that increasingly needs to be made as people substitute political correctness for informed discretion. If you let PC think for you, you're not actually thinking... you're just running on doctrine like a 14th century Cardinal.
