On the contrary of the Nazi, the Commies were never judged for what they have done (despite 10 times the dead the nazis have done and thus during peace time).
There weren't any Nuremberg judgement of the communists and the impishly guilty Serbian leader Milosevici is supposed to have been the only one guilty for that all time communism mass murdering.
Nearly 15 years have passed and the Soviet Union is not a threat for anyone's freedom anymore and chinese communism is fading and those times are even forgotten by many that lived in there. The same applies to the nazis. Those anti-freespeech laws are damn stupid. I am wondering if they aren't made to support the jobs of the people living in those official human right organizations paid by governments to spread that filthy political correctness.
I don't bother about commies marching for the defunct Soviet Union nor those praising Hitler. Why ? Just because this is not my opinion but I certainly prefer having people expressing various beliefs and opinions peacefully as far as they do so for me.
Now about cemeteries been desacralized every week by arabs in European countries, the problem which appears as an anti-semitic threat (do they ever consider that arabs are semites too) and often (wrongly) considered as a resurgence of nazism is much more serious. People relieving their hatred on non living will not change their opinion, nor their behaviour and their children won't either.
What happens in Latvia is much of a joke. You can disaprove, be shocked or whatever, it is the only thing you can do against it in the best world we are supposed to live in.
That said the only matter where there could be a complaint is public education and EU may consider interference in such cases.

Another way of doing would be to analyze more seriously how and when those opinions appear and spread and further become a threat. The answer is always when jobless people meet each other to put the world to rights.
