yeah I think I gotta go with claw on this one, a musical preference is one thing -- e.g. "I dislike rap music", but this is a blanket negative statement applied to an entire nationality. how is saying "Polish people all have some inherent quality related to their polishness that makes them bad at x" qualitatively different than say "black people are less intelligent" ? plus your overall tone in this whole exchange is passive aggressive, and now you've also made an insult of someone's intelligence!
war2 forum actually seems incredibly biased against the polish, constant insults against polish people & polish culture happening that never get taken seriously. war2 poles have earned this one for all the shit they've taken over the years!
