Words don’t make people shoot others.
PC says to not say certain things ... Because they don’t want those things said. So they try to control your speech by calling hate or saying it caused the shooting.
If certain things can’t be said, how do ideas get out?
This is going to wind up as an episode in “South Park”, if for no reason other than the fact that Park County, Colorado, was the most recent domicile of the shooter, and he will turn out to be a prominent citizen of South Park in their version. Jimbo Kern seems like the most likely to be endowed with this persona, or at least he would have been “best friends” (along with Ned Gerblansky) with Robert Lewis Dear.
