This, in a nutshell, just goes to show how many fucking idiots defending CK miss the point. Gross, offensive, tasteless humor is absolutely okay in comedy. Bits about assholes or your kids sucking or killing your dad are okay. No one wants to stop that. People dying in car accidents, sure. Joke about it. Fuck, joke about school shootings as a thing that happens. When it becomes punching down and the equivalent of an alt right dickhead's twitter feed, that's where the line is drawn. Targeting and attacking marginalized people or specific victims of an atrocity for the lone purpose of attacking or targeting them is the problem, not joking about controversial things.
