I personally dont like when people say "polack" i take it offensive and i usually correct them. I am a polish woman, and if someone is going to refer me as "polack" i will and i do get upset. So i guess everyone looks at it diffrently, you dont have to punch a person for callilng you that, but if you dont like that name i would definately correct them and make sure they dont call you a "polack" again.
