More proof that socialism is all about repression

The opposition Socialist party managed to limply pass a law through France's lower house of Parliament making denying that the mass killing of Armenians by the Turkish government during World War I a crime. Naturally this infuriated Turkey, but that's not really the issue. The issue is that even though denying that fact is stupid, this violates the inherent right of people to say whatever they like - even when that stuff isstupid and damaging, like, say, socialism.
