A Jew is a Jew No Matter What

I was reading an article tonight that I found interesting. The author questioned why Christians are not interested in making any cultural group other than Jews give up their cultural identities. He pointed out that Hispanic Baptists worship in Spanish, celebrate Cinco de Mayo and other Mexican festivals, and eat cultural foods without getting grief from anyone. Jewish believers, however, are expected to give up all of their festivals and kosher foods if they want to be "one of us." My brothers, this should not be.
