The article makes it clear that militant groups like 'right sector' are a small percentage of the Ukrainian population with no representation in parliament, so your "complaint" is nonsense.
What's really bothering you is the fact that the 'pro-democracy' mask is slowly being pulled off the violent fascist core of the Ukrainian anti-government protest movement.
Sorry, as mentioned, I didn’t read the article, couldn’t make it through the headline “far right militants”. But if you say that there’s admission that “far right extremists” are a minority and there is a much much bigger majority, then there’s not much of a problem with this characterization. There won’t be a problem at all if the story had been about the much bigger majority, but that would be too much to ask for.
It’s not that hard to identify what is at the core of anti-Yanukovich revolt (fine, I’ll spell it out, it’s rejection of Yanukovich, his fat Sovok face, and the billions he stole) Russians can either face the fact they’re supporting a tyrant, or continue to ignore the real cause and blame it on extremist nationalists, Soros, CIA, US State Department, Bigfoot etc
