No, most EU countries have laws in some form that prohibit Holocaust denial. But as with any country that has the rights to freedom of speech, these rights are inevitably balanced and restricted by other laws.

This is a good thing, because while freedom of speech is important, the general wellbeing of the population and preventing people getting hurt is important as well. It is my belief for example that allowing racist remark under the banner of free speech, hurts more than it helps. It leads to an overall negative impact in the wellbeing of the population. I think the same balance was considered when prohibiting holocaust denial.

Question: why use a throwaway account?
