Calling bigotry callouts witch hunts? Nice Trumpian rhetoric. Completely removes any semblance of blame from the called-out, while simultaneously accusing the caller of either ignorant, needless destruction and/or deliberate targeted 'cancellation'. Thing is, it's bullshit and we all know it. I agree that the publishers should have taken a different route, but if anyone, blame them. Don't blame us, nor accuse us of being "perpetually offended", etc. There's a significant difference between the straw comparisons you and others sharing your view on this have made and what's actually happening. In this case, even if it WAS due to a direct callout or anticipation thereof, it wasn't "everything is racist and must be torn down" or anything of the sort. The offending images were in fact offending, with pretty blatant stereotypes or racist depictions in each. This really shouldn't be that hard to understand, but I guess I'm asking a little too much from mister "white privilege doesn't exist".
In addition, there's the matter of context. In this case, this small move by the publisher snowballed into people digging up Dr. Seuss's rich and absolutely wonderful history as a creator of extraordinarily racist propaganda! Ironically, had the right-wing crowd not immediately reacted as if some angry mob of torch-and-pitchfork-equipped ess-jay-double-yous dared to erase IMPORTANT LITERARY WORKS THEY HELD SO DEAR (despite the books in question being laughably obscure as is, compared to the more well known ones you mentioned that lack that kind of offensive material)... we wouldn't have the perfect contextual evidence we needed to defend against said absurd reactions!
This time, try actually putting yourself in the shoes of someone of a minority group. In a somewhat obscure book, there are images and descriptions that either paint your group in a negative light or overly generalize the entirety of your group into a stereotype that has been previously and historically USED to paint it in a negative light. Does it warrant completely stopping the book's publishing entirely? Eh, probably not, though it depends on the frequency and the context. Is it bigoted enough that taking offense to it is justified? Of course it is! If minor wrongs are allowed with zero consequences and negative reactions thereof are frowned upon, then they eventually become normalized- into the very sorts of privilege and systemic bigotry you still deny to this day.
