Nobody buys into their delusion. TPTB push it to forward nefarious geopolitical goals, but they dont buy into it. The deranged leftists prostelytize because they are told to and it fulfills some innate need to virtue signal, but unless they are mentally ill themselves they understand the truth of the matter even if they dont speak of it. The rest of the 96% of us reject it outright.

So IMO nobody really buys into it, it is just a narrative for control, power and the destruction of western civilization.
