Neither am I a parent. I'm open to changing my mind. This isn't a topic I thought about until recently. But removing items from a library should be a cultural red line for a free society. A restricted section, where one needs e.g. parental consent to access the books, seems to square the circle of not letting one group take away another's access to information while keeping parents in the driver's seat.

Note that my argument begins and ends with libraries. I don't really have an opinion on classroom instruction and materials.
