I see where you’re coming from, and I also disapprove of beliefs and ideologies which demand ignorance. However, there’s no impartial principle which can determine who is ignorant and who isn’t - I have, for example, been called ignorant because I refuse to read the books that vaccine conspiracy theorists suggest to me. If their views became mainstream (and if I had children) I would want the option of withdrawing my children from a class teaching those views, even if technically the class would not be forcing them to believe that vaccines are harmful.

Ultimately I don’t want to wield any power against my ideological enemies which they would then be one election away from wielding against me.
