Really, why anyone is bickering about vernacular in the wake of such a tragedy escapes me. This is a fucked up, horrific act which occurred. You're response should simply be to condemn it, express sympathy for those victims directly involved, and move on.
It's not another platform from which you're supposed to spout your bigoted rhetoric.
You guys are arguing over definitions of words, when the simple fact is that a fucked up human being took the lives of dozens of other humans.
Stop usin it as an excuse to flex your nuts. Maybe some of us knew victims who died last night.
