Oh, not disagreeing with you about the open racism of some if not most of the permitted marchers.

They are nothing new. Those yahoos have been around for decades preying on the marginalized and malcontent.

Society treats them like the occasional foul smell that drifts in from the sewage treatment plant. A necessary evil in order to protect our freedom of speech.

Society is in no danger from them. You don't need to suppress the speech of an idiot. Just let him speak and he will quickly eliminate any doubt as far as society is concerned.

But if the quest to end racism drifts into a witch hunt, which it is, and racism accusations become a club used to gain advantage and bash other people over the head, then their ranks could grow.

So they are not the danger. Our reaction to them is where the danger could lie.
