It seems like you are making a mountain out of a molehill on this one. I dont think many of the implicit bias that people may experience manifests into an action that is significant. I can see how that could be true for some of the older people where they might say things that sound a little offensive, but I dont think it is a problem that carries a lot of weight. I would say that people more want to try to solve a problem that doesnt really exist, and in doing that they can create a new bigger problem.
