Probably because sound thinking, and the basis for it, is a real threat to some people.
I read some pretty skanky books in high school. After I’d read them I wondered what all the rush was for me to read them.
Look, I’m not in the business of advocating the banning of books or setting limits on what movies portray to our kids. I’d just like to think that a few movie makers and book writers could produce products that would teach our kids some positive things, without dragging them through filth to do it.
Today only leftist propaganda qualifies as material that needs to be taught, and as for dragging kids through filth, every aspect of a wholesome value system will be destroyed if at all possible.
Do you believe that a school, in exercising selectivity in student assigned reading, and in choosing the good over the bad, is "banning books"?
