We bomb brown people because we can get away with it. That's more opportunist than racist, but it's still racist.
As soon as "white" people start doing the same crap, it happens to them too. I'm guessing you're wishing away that pesky little Balkan conflict a few years back, where we bombed white people for, among other things, slaughtering olive people.
Pretending that it's skin color that makes ISIS a fair target for air strikes is the worst sort of craven intellectual laziness.
