It’s totally okay to be proud of aspects of your heritage. It’s important to also own up to harm done by your ancestors too, especially when you benefit in tangible or intangible ways from that history, which becomes less expected of you the more injustice was done to your ancestors vs done by your ancestors. However… “White” is not a race, white is a skin tone, there is no universal white heritage, even “European immigrant to America” is far from a monolithic heritage. “Black” being considered a heritage confuses some people but that’s because “black” is shorthand for two things that aren’t directly skintone. “Black” refers most commonly to the shared experience and built/rebuilt heritage of the descendents of slaves who’s culture and heritage were stolen from them, brought mostly to the Americas from West Africa, and then systemically oppressed for generations. “Black” can also be used to describe people who share the experience of oppression based on their black skin color regardless of their specific history.
