"It's the popular thing to assume these days. It's also very insulting to Russian people in my opinion. But I guess it's ok to be prejudice towards some group of people but not others."
Is that not the comment you were calling correct?
That's what "the person [you] replied to" was talking about, that use of the word prejudice.
This is a discussion about the Russian government, it doesn't really have much to do with Russian people in general.
That is what the person I replied to actually said, and the comment I was clearly referring to; the point being of course, that a discussion of the Russian government has no more to do with the Russian people than the Russian government does.
