You might want to review your home state laws. Legislation passed in Georgia, Florida, and Mississippi in 2022 regulates how the teachers can discuss racism, sexism, and issues of systemic inequality in the classroom.
What the bills say, and what some news articles say the bills say, are different. For example, in Florida, it is prohibited to teach that:
"1. Members of one race, color, sex, or national origin are morally superior to members of another race, color, sex, or national origin.
2. An individual, by virtue of his or her race, color, sex, or national origin, is inherently racist, sexist, or oppressive, whether consciously or unconsciously."
And so on.
Teaching about racism, sexism, etc. being bad and about their history are allowed and a standard part of curricula.

Parents in different communities have different opinions on what they do and don't want their kids to read. That's OK. It is up to them how their kids are brought up and what they read. If one community wants Huck Finn in the library. OK. If another doesn't want it. OK.
If a parent wants his kid to read a book that isn't in the school library, the parent can get it from the public library, buy it from Amazon, buy it from the used-book store. There are lots of books I want my kids to read that aren't in the school's library. So, I get them for my kids. No biggie.
