American history has a track record of valuing the lives of certain races over others, so I don’t know about that “same race as us or not.” You’re simplifying an extreme horrific tragedy. People who do not have an authoritarian nature could and hopefully do hate Nazis. The six million Jews who were murdered by the Nazi regime (World War 2) is all the reason you need. Reducing that one down to a character trait instead of genocide is problematic. That’s nowhere near the same as saying (for example) you hate people who are always tardy for work.
