No group has done more harm in the last thousand years to Jews than White Christians. Even the current Christian support of Israel is warped. Read up on why exactly many Christians in America want Israel to "succeed" and you'd be shocked. It's all part of a warped end of days, second coming, apocalyptic fantasy. Many American Christians don't care about Israel or Jewish people at all.
They don't actually care about us, just their idiotic fantasies about Jesus' return to the Jewish homeland. After that, we're back to being the ones who "betrayed" him.
