Yeah, well, that's why Prejudice and Racism isn't just presuming bad things about people and acting worse towards them due to their ethnicity, it's also presuming good things about people and acting better towards them due to their ethnicity - in both cases you're presuming some are better than others based on things which bare no relation to the worth and character of an individual such as race, gender, sexual orientation and so on.

Just because somebody is a Jew does not mean they're better or worse than anybody else - it's their actions and what they support that should guide our judgement of an individual, not something they were born with.

Don't take this badly, but all this time you've been Prejudiced (and one might even say a Racist) even though you probably thought that wasn't the case (I suspect you believed it was the contrary, even) because it manifested in you assuming good things about people from specific ethnicities and treating them better than others rather than as negative presumptions and treatment (though by assuming some people are, due to their ethnicity, better than others and treating them accordingly, you are actually negatively discriminating against everybody else), and what you're seeing now, clear as day, is that the bad people within an ethnicity whom you judged better than others purely based on ethnicity, have weaponized that "positive" Racism of yours and of others like you into political and social capital to let them do the same kind of thing as the Nazis did, with impunity and even support from people who if they weren't prejudiced would've judged them more fairly (something which might very well have stopped this Genocide from ever happening).

The best posture, IMHO, is to try and not be prejudicial towards people no matter what their ethnicity, gender, sexual orientation and so on are, and that includes the kind of prejudice made up of positive presumptions.
