I believe there are many reasons that we as Christians should not overlook the sad history of antisemitism that plagued our past. One of the most practical reasons, I believe, has to do with relational barriers between Christians, Jews, and Muslims. Christian antisemitism is not the only barrier that could exist between these three groups of people, but if we are careless and ignorant in our engagement with these people we might build more walls than we tear down. When we come to this conflict, it is important to understand the History of where we came from. We need to know where our side has failed just as much if not more than the other sides. If we attempt to engage meaningfully in this conflict but do not acknowledge the failings of our spiritual past, we will have no voice. This is why it is important to slow down and listen to both sides. To actually seek out what barriers exist. Then we can more effectively move forward in a direction of reconciliation and healing. Relationships are a powerful thing that God uses to spread His Kingdom. A good relationship does not tend to flow from ignorance and a desire to downplay and hide past grievances.
