Hate to appear to pile on, but diagnosing a particular issue is the first step towards resolving it.

You say that in a healthy society that you propose, blacks would not be disproportionately engaged in criminal activity. But if anyone who attempted to address this issue were punished, I can just as easily see impunity resulting in even worse outcomes. And if your other proposals are successful at combating black criminality, then there would be no need to punish people making such comments - just say, what are you talking about, they're not more criminal than other groups.

Here in Europe, you are not allowed to talk about the depredations of the rapefugees. Does this result in them raping less? On the contrary, they rape just as much as they want, and the politicians protect them.
