It's quite possible that EU member states simply have different philosophical views and considerations as to the value and effects of freedom of speech. In fact, the United States is quite exceptional, but it too draws the line somewhere (assault, threats, child pornography).

Yes, that's probably true. Just because I say repressive in a pejorative tone doesn't mean the people who live in those states are bothered by it. They may prefer not to have to hear some of the speech I find regrettable but a necessary cost of freedom. (I think there's a very good argument for drawing the line where the US does and not somewhere else, but that's a different matter.)

Not sure why you're being downvoted. Personal freedoms are awful in the EU, but it's in exchange for increased safety and economic stability. Obviously an amazing tradeoff.
