Dude, we do have to give a damn about the past and the mistakes we as humans have done in the past. We have to teach about our wrong doings to our kids so that they don’t let such mistakes happen again. Pretty much all countries in the world have suffered from the crimes of western nations and their imperialism in the past. Jews are not exlusive to this. But that doesn’t mean that we should keep hating each other based on what the forefather of a group of people have done to us in the past.
