Where exactly ayatollahs talk about people rights and free speech? Comparing J.S. Mill to a bunch of religious maniacs is a bit far-fetched.

The fact that Mill wrote those words 200 years ago does not mean they are incorrect. We stick to the rules of Roman law in many aspects, although it was written pretty long time ago. Pythagoras formulated his theorem quite long ago too, yet we still learn it at school.

There are certain ideas that seems to be universal, that just make people lives better. People tend to challenge them and thanks to that we get goodies like Communism and Nazism.
