That isn't necessarily an all-encompassing assessment of public opinion.
Those survey questions don't really allow for very much nuance.
There seems to be a three-way divide amongst the general public:
1.) "Systemic racism DOESN'T EXIST, and racism, for the most part, isn't a problem any longer"
2.) "Racism can be systemic, social, and/or cultural, and, therefore, it is directed at different people within varying context"
3.) "Racism is ONLY systemic, and NEVER social or cultural (individual or interpersonal amongst groups)"
Perspectives #1 and #3 are on the opposite fringes. Their adherents normally dig in their heels and dismiss any dissenting views that anyone else exhibits.
The middle statement -- which, not coincidentally, is where I, along with millions of other people, fall -- appreciates/welcomes nuance, and empowers global citizens to look at racism on multiple levels, peeling back multiple layers, in multiple contexts.
Perspective #1 is clung to by the anti-CRT faction.
Perspective #3 is clung to by many (not necessarily all) within the pro-CRT faction.
Perspective #2 rarely ever seems to receive a voice from the mainstream press or in academia, even though it most likely is closest (out of the three) to where most people are at.
