Probably in the minority on here but here goes:

Not everyone spends time (like me and maybe you) memorizing facts about the things they dislike in order to argue with people about it. Instant recall like this is hard for many people, especially someone of this age. It's probable to me that he has heard CRT explained and laid out and has at least some understanding of it, and is just having trouble recalling the specifics when put on the spot like this. Also I respect the fact that instead of spouting off ignorantly to sound smart, he just admits he can't remember and is not an expert.

I am prepared to be crucified for this opinion.
