Christianity and Judaism

I am kind of having a hard time thinking of a question or an opinion on our current topic of discussion in class. I did, however see something in the book that kind of interested me. I saw that the Jews were continually persecuted by the Christians. The Jews would be forced to live in ghettos, wear certain caps, and were forced out of industrial and agricultural work. I just can't see the justification of that. It's just so wrong and hypocritical of those Christians to do such things to them. I mean, the Christian religion is based off of Judaism! But I'm sure there's debate over that topic. What would a Christian these days feel like when they know that such things were done by Christians? That's not even just the persecution of Jews, but other things such as the Inquisition and the Christian holy wars against the Jews and such. So I kind of wonder how a Christian feels these days knowing such things were done by their Christian ancestors.
