Imagine if these offended celebrities had to be black, or Eastern European or Muslim for a day. Seems any old attempt to throw anti semitic mud at JC by certain elements within society. It's definitely not Jewish people though - loads of Jewish people support JC, you only have to look on twitter to see.
My very Pakistani name is pronounced in an anglicized way, it always has been because the English language doesn't pronounce letters in the same way the Urdu alphabet does, so when my name is pronounced by English people, they pronounce it as they read it or understand it according to their understanding of language. I've gotten used to it. if someone tried to pronounce it correctly, it wouldn't offend me. It might surprise me because it seems the only person who pronounce it correctly are Pakistani people but offend? No.
