If "yid" means a Jew it is still a quote from Cartman to me and wouldn't really matter.

Was there anyone he tried to offend or just said that for no reason?

And i think Jew can't be so bad to say in here as we have a guy named Jewwwww.
Well couple W's more but anyway.

RE-EDIT: So Yid means Jew...

Soo he said Jew Jew's fucking kyle?
