OK?

Why is it forgivable for an actor to attack another on the set and scream hate speech pertaining to gay people (when he is sober), and it's not ok for someone who was clearly drunk and not in his right mind to scream the same kind of hate speech to a particular religious group and be continually chastised for it? I am not saying either is ok by any means, but one is obviously more acceptable than the other. I don't get it.
