I’m sick of that label/epithet getting tossed around. No it isn’t. Racism is a prejudiced attitude towards individuals on the basis of their ethnic or national origin. The comment demonstrates none of that.

Seriously, is the world really a better place if we can’t laugh at one another and especially ourselves?

Moreover, it sounds to me like the commenter is showing a decent level of respect (or sportsmanlike admiration) towards Russians in general.
