Do you even understand what you wrote above? Sadly, the logic is absent in your statement. How can avoiding provocation of religious minorities be equated to getting rid of ethnic minorities?

Oh, and "freedom of speech" does not equate to "freedom to insult".
Maybe because he has been seen as the "bad guy" by the west. so he needed a good excuse for getting rid of any non Christian symbols from the public which Russia has been doing.
Oh, and "freedom of speech" there is a reason freedom is put in that phrase. If you cant handle someone pointing out flaws in your views and you deem that as insulting then life is going to be hard for you.
