...whose nom-de-guerre is "Chorniy"

I thought "Chorniy" was the Russian equivalent of "nigger". It's what Russians call the Georgians and other darker skinned people from the Caucasus.

No, actually it's the direct translation of the English word "black". Using it for the Caucasian descent people is really meant to be offensive in the contemporary Russian, because they have nothing to do with the Negro race.

You know, I think right sector is pure neo nazi. But I draw the line at making fun of anyone’s nom de guerre. That’s just wrong.
And I’m betting:
A) it’s meant ironically, like when the biggest guy is called “tiny”.
B) you wouldn’t say that to his face.
