Your last paragraph says a lot. Actual differences exist, both physical and cultural. What matters is when they matter and when they don't. Sadly, we often err in that. In a perfect world we would all enjoy and value the difference without all the negative judgment.

My last comment was more with regard to the use of political inflammatory accusations. I actually see the political left as more racist than the political right in some matters, but I don't make assumptions or accusation about racism of whole groups or its individual members. That would be just another form of racism.
