Sorry, my intent was to suggest that the sentence was pejorative towards Russians.

I may have been unclear and reading up I may have misused the word - can pejorative apply to a sentence or just to a word or phrase?

Yeah, I was just not sure if you were using it on the whole comment or making a silly joke. And I think it's a word only, at least in a language I speak naturally. That is not English however.

Any word can be a pejorative if used as such, you hacker.
