Well given that the vast majority of schools can and do teach it effectively, the idea that it can't be done seems excessively fatalist. But if we do accept that it's just too high of a bar to ask schools to contextualize To Kill A Mockingbird in such a way that the literal lynch mob killing a man are not presented as role models to be emulated, then shut the school down. The kids are better off at home staring at a blank wall 8 hours a day than being exposed to that level of incompetence. Banning books to deal with teachers who can't teach is like sticking a "0 Trans Fat" sticker on an improperly stored barrel of radioactive waste - it is worse than not even addressing the problem.
