I don't think you even know what a clown you are. You previously admitted (twice) to be ignorant of a theory/concept (CRT), but then later say most people opposed to that theory don't know what it is. Do you understand the problem there?
You then are confused enough to ask "why is it my burden to research it?" The glaring and obvious answer is that it would be your burden to research something you admit to being ignorant of so that you could then credibly say that most people opposed to it are also ignorant. Otherwise you can't. Do you understand that?
Your vague, generalized and highly subjective "point" isn't a point at all. Under that "point," and the unstated conclusions you appear to be drawing from it, literally anything -- intelligent design, flat earth, Marxism, alchemy, eugenics, astrology, War of Northern Aggression -- could be taught as doctrine or fact in schools without concern.
I'm not on the right.
I responded intellectually to every bit of confused logic you posted. You got answers to your question from several sources. Everything else stated was supplemental to that.
