I'm white. I decided long ago that everyone needs to treat everyone fairly. Part of that is basing promotions/etc on merit, but part of that is understanding that people are different and have different strengths and weaknesses, some of which are because of the culture they come from.

This applies equally to whites and people of color, rich and poor, nationalities, and more. I have yet to find a culture that didn't have both problems and benefits when you generalize about them.

I've also yet to have that generalization be actually useful when evaluating an individual.

But I have to ask: If I stop someone from discriminating against you, with or without your knowledge, is that really "destroying your culture"? If I'm in a meeting and stop someone from ruling out a potential candidate because of skin color, did I harm their culture?

I can't see how that's possible.

I could see how "culture" changes over generations as economic status changes. But I'm certainly not going to refrain from helping someone because I think there's a chance it'll change the culture of their grandchildren.

That said, I've been in situations where I could "help" someone avoid some racial prejudice and was asked not to by that person. As they wished, I did nothing. I didn't like it, and I still wish I could have helped them, but I felt I had to honor their wishes first. (The person I'm thinking about eventually quit from stress and moved out of state.)
