freedom of speech is not considered a human right in Europe though

From the Charter of Fundamental Rights of the European Union:

Article 11

Freedom of expression and information

1. Everyone has the right to freedom of expression. This right shall include freedom to hold opinions and to receive and impart information and ideas without interference by public authority and regardless of frontiers.

I think you are wrongly informed.

Ironically, the Chinese constitution expresses a similar right.

And now look what that means in reality. Virtually every single European country forbids certain political speech (mostly this is about fascism or communism, but Hungary has started to use this to surpress LBGT expression). And that's just the start, once you dig deeper you will find all kinds of laws chipping away on that "fundamental right".

> Virtually every single European country forbids certain political speech

This is not true.

And I can read all about that in a book without getting my organs harvested.

Yeah, instead you will get blown up to pieces by Howitzers.
