Philosophical differences here don't mean racist, but if that's the only way you know how to express your frustration of not understanding then it's OK man.
I think being forced to ask every patient if they are hispanic or non is a problem, I think having to distinguish race on every government document is a problem. I think you guys that focus on skin color every topic is a problem. I think the people who opine "someday we'll all be the same, the same color, we'll all look alike and things will be super" are a problem.
I see nothing wrong with recognizing differences in people and embracing them. It's the generalizations that are wrong.
