These words are the essence of your use of the No True Scotsman fallacy. Christians persecuted the Jews for nigh on 2,000 years. Your personal disapproval of what Christians did does not make them not-Christians nor does it make what they did go away. In the real world, Christians are what Christian do, just as Scotsmen who wear underpants underneath their kilts are Scotsmen, whether one likes it or not.
So the Bible has no role to play in determining who is a Christian and who isn’t?
