I agree with this. There's a lot of talk about book banning but it's impossible today. Examples of what is called a ban is a library not having a book. That's not a banning. Amazon not selling a book is also not an example. If someone has an actual example of a banned book I'd love to know about it. Heck, in the US they can't even stop the spread of plans to make your own gun. The internet has ended this issue.

There are books that are culturally frowned on though.

First two to come to mind. Reqd both and both are worth reading.
