All that quasi-intellectual gibberish. Common sense isn't too complicated you know.
I was thinking more along the lines of perceived anti-Polish/Jewish/whatever views.
There's a difference between something that could be percieved as slightly negative, and something that's obviously damaging or humiliating.
Should someone posting negative things about Germans, Russians, Jews, Poles, Brits, Americans, Immigrants, whatever be censored?
If the poster's only intention is to ridicule, insult, flame, troll, bash, discriminate, degrade, humiliate or slander, and seems to have no other arguments besides discriminatory reading material, then yes, that should be censored. (Kicked off permanently.)
If one user writes the Communist Polish secret police was primarily run by Jews, and another writes that concentration camps were staffed by Poles, which should be censored? Both? Neither? Do we censor facts? Who does the fact checking?
Neither. But you should probably close the thread and consider deleting it if such posts get reported more than a couple of times. I don't mind strong language or strong opinions at all, but I do mind it when people feel deeply offended, humiliated or genuinely upset. If people tell you such things, the alarm bell should ring for you guys. You shouldn't let certain things drag on for too long.
Just common sense.
