russians were silent during Chechnya, during the Yukos case, after Putin's comments on Kursk widows, after killing of Politkovskaya, Nemtsov, and so on and so on. Look at any russian popular media in early 2000s and you will see a huge amount of really casual racism, with "Brat 2" being the pinnacle. Nobody spoke out against it.
Just because they let it fester for so long that now they can't even protest is still on them.
