I think you go against God if you go after anybody out of prejudice or irrational hatred.
I do believe the forces of evil in universe whether we call that Satan or whatever has targeted God's chosen people for all of its recorded history. I also believe God has saved at least a remnant of those people to carry on as indicated in Biblical manuscripts and as observed in more modern history.
The Jewish people have been overcome and and dispersed by various conquerers as recorded in Biblical manuscripts. It is believed the later New Testament manuscripts were written after the Romans drove most of the Jews from Jerusalem and Israel in 70 A.D. and destroyed the temple there. That accounts for Jewish populations throughout Europe or, more specifically, what was once the Roman Empire.
In their much more recent history, most were driven from Russia and what is now the Ukraine in the late 19th Century and early 20th Century and most from Germany in the mid 20th Century.
Yes the remnants from those histories are of European descent but that makes them no less the Jews who are God's chosen people.
These are amazing people. They constitute 1/5th of 1% of the world's population but their contribution to the advancement of civilization and the greater good. They hold more than 1/5th of all Nobel prizes awarded and are credited with many innovations, inventions, creations far beyond what their tiny numbers would expect.
Yes Christianity I believe is of God too. The JudeoChristian history has influenced the entire world far more than any other events/forces/concepts put together.
But I personally believe it goes against God to scorn the Jews.
