This is a "by country" thing, there is no European constitution and all European law is aimed at countries, not people (but some stuff is redacted like: "countries should have a law that does this or that"). Quite a lot of nazi comments (nationalist stuff, the idea of having been wronged in the last war, the idea that your race is superior, etc.) would probably fly in many countries I think. It's mostly the call for murder or physical arm that would trigger sanctions in many countries. And also groups with history of violence (like violent soccer fans or political activist whose demonstration always turn violent).
