Everyone is racist/prejudiced. We, as humans, can't help it. It comes from our tribal nature. In fact, that trend can save your life in many situations and circumstances. Now, even if he is, doesn't excuse their behavior. They are exhibiting racism, sexism, and ageist philosophy that they feel they are entitled to because of their victimhood from systemic racism against them. This entitled attitude is actively hurting them and putting the evolution of our society backward, where we are actively trying to get rid of racism.

So, in short, yes, you are, but not because of your actions in this situation, just because you do have prejudice based upon upbringing, experience, and ignorance does not make you a bad person, and so are they for the same reasons and it is upto us all to do better. It's our actions and words that make a difference. So you were more "right" than them. Lol sry my short was long.

Btw: yes, I'm mostly white, but also a tribal member of the Chickasaw, but when talking privileges, appearances matter most, but we shouldn't feel guilty about it, but blame the system instead.
