Asking art- good or bad- to be politically correct is ridiculous; and anyway the "artwork" is a composition, not the sum of the individual images.
And yes, art can be racist or misogynistic or problematic in other ways. There's nothing wrong with calling it that. Or do you think it's cancel culture to call "Birth of a Nation" racist?
Not explicitly, no. But it seems to me to follow the well known pattern of "hey, look, I've found something damning buried among X's old stuff".
Yes, art can be racist, it's just not the metre you use to judge it.
Please. "I'm not saying we should do something about it, but oh my gosh, look how offensive it is".
