I definitely see your point around a lot of people trying to be so inclusive, they end up being somewhat racist. But I see this more of a lack of proper cultural empathy/education -- go figure, Dunning-Kruger is everywhere all the time. But as you said,

So why would we ban the books, rather than encourage reading them and having the more meaningful discussions focusing on heritage rather than identity?
As a slightly more abstract aside, identity anything to me is a slippery slope because it will always automatically encourage one to make assumptions; it's a mental shortcut to say Person A == Person B iff PersonA.identity == PersonB.identity. Given that education is hard, learning is hard, and life is hard, I think we need to at least emphathize and appreciate that teachers and the the education system in general need to often fall back on these sorts of mental shortcuts. But that's we need to really invoke our right, privilege, and duty of grassroots participation. Why not walk into that book club that's overcompensating and help them learn what is making you uncomfortable? You might be surprised at how ignorant they were of their own mistakes and that they're willing to learn from your perspective.
