Because the propaganda machine serves the suckers' self-centric worldview first and foremost, "unites" them, galvanizes them, and exploits their selfishness and greed to weaponize them against "the other".

That's what is so insidious about it, and the only real defense for those of us who are "the other" is deplatforming and throwing a wrench into the propaganda machine.

You are debunking something I didn't claim.

Can you answer the question I posed, "Today's news is full of exactly the same attitude displayed by this person. Why are people not rejecting this today?"

Because the people with the same attitude as that guy are—mindboghlingly—in power.

There are plenty of people who reject that rhetoric. That's what BLM is, as a currently-relevant, specific example.

The problem is the aforementioned undermining and exploitation of selfish and self-serving attitudes and actions has led to an unreasonably large base on the other side, giving the illusion (at least to you) that nobody is rejecting it.
