Meh. It's probably just a fad. Years from now, we might look back and laugh at it. Or not.
It will be a "fad" I suppose, as soon enough of society is sick enough of them to tell them to shut the hell up, or at the very least ignore them. People who appease them out of political correctness, or even those who just pat them on the head, only exacerbate the situation.
Ignoring them could be all it takes*. To paraphrase a comment at the URL, a couple of billion white males went to bed at night happy and woke up happy, not giving the nitwits with the "death to white guys" or whatever signs, a thought.
* I realize I'm as guilty as anyone when I post similar "look at the imbecile" threads here.
