The most likely cause of death for me on the next 20 years, as a white man in his 20s, is suicide. A major part of the reasoning for that is men typically struggle to reach out and talk about issues. A contributing factor I think is growing up around phrases like "man up" or "stop being a girl". Obviously anyone who says them isn't saying "bottle up serious issues until it becomes too much" but that repeated learning does stick and despite times changing and there being far less pressure now to be an alpha head of family type guy, the issues continue to affect us.
I don't see any reason that same repeated learning from a young age wouldn't also apply to black/white language if there's an overwhelming imbalance.
Muhammad Ali famously gave a speech on exactly this, though he also covered cultural references as well which is a broader scope: https://www.bbc.co.uk/news/av/world-us-canada-52988605
