Why do you think absolutists have no problem with this law? Did you just make that up?

I for one do not support the law and I would consider myself 99% an absolutist.

Arguments about concepts like hate speech tend to pull out a large number of self-identified free speech absolutists, arguments about restricting access to books in libraries ends to draw out very few. You might find it intresting to dig through the history of past discussions right here on HN.
