They're hiding their power level, even from their own followers. You can't just say:

"Each and every single white person alive today, and many non-whites as well, who make any amount of money, or incur any general social benefit from established institutions or capitalism are white supremacists, by default, from birth. Each and every single white person alive today is guilty of the crimes of their race. In order to compensate morally superior races for the plight that all whites have oppressed them with, white individuals must lose all of their material possession, and become absolutely obedient to the orders of their racial betters when it comes to re-distributing wealth from inferior oppressor races & allied minority individuals to superior deserving people of our designation. This includes self-sacrifice to the point of death. These are not requests, it is a moral imperative for a white person to volunteer themselves to be used as a human shield. You will not, under any circumstance, be forgiven for the crimes of your race."

and expect most normies to listen to you.

If the Left showed their power level, most normies would reach for a gun.

Instead they smile and use reductionism to hide their intentions. Look at what the SJWs were doing with Feminism. They kept saying "Being a feminist means you just believe that women should have rights!" because they did not under any circumstance want the general public to be aware of the details of their actual ideological framework. They swept their own narrative history under the rug to sell feminism. They would never even acknowledge the history of the things feminism actually did.

It's very similar to what most cults do, like Scientology. People don't realize much now that the whole Xenu thing was vociferously denied by Scientologists for years. Within Scientology, this is considered "hidden knowledge" that would literally kill people who heard it if they were not at a certain rank within the organization. Scientology still denies Xenu, and it's their own narrative. They do it because they do not want people to actually hear their whole position, because they know it's repellent.

Consider the opposite perspective from Science. A good scientist, or at least someone knowledgeable in science, won't hide a fucking thing from you. In fact, you have to try and keep them on track from going into too much detail and confusing you. What they know, they know because they've gone through a lot of work and learning to explain how things interact. They don't want to be reductive, but you have to ask them to be reductive or you'll just be thrown for a loop.

They don't want to say Critical Race Theory, because if they did, people (including their own useful idiots) might look shit up independently and start reading on their own without having a lecturer 'guide' them to the right conclusion.
