That argument is a bit of a paper tiger.
I'm not talking about things that happened last century, I'm talking about something that's happening right now.
Of course human rights violations are much much worse in Russia. I certainly won't be going there for holidays, as I might love it so much I'll never come back.
I'm a big fan of free speech, and if people are calling out the horrors going on in Ukraine that might go some way to stopping it, assuming enough people actually care and are outraged by it.
Likewise when Snowden called out some of the things that the USA were getting up to, that might stop them. Although looking at the bill that's just passed to extend their snooping powers on American citizens (written about today on this very site), it seems that not enough people actually care. At least it's legal now.
This hardly makes me a Vatnik, but just pointing out that we in The West should hold ourselves to a standard that we expect of the rest of the world. Otherwise it makes it hard to criticise them.
