You’ve hopelessly muddled your point about capitalizing the “W" in White when referring to White people by mixing in all sorts of incidents. If the McCloskeys had not come out with weapons to defend their home, would you have reverted to a lowercase “w"?
The other big problem is that many people do not fall into the White or Black categories you have designated. What about the majority of the world population that has its origins in Asia? I am referring to people from China, India, Japan, Indonesia, the Philippines, and all the other countries of the East. What about people of mixed racial and ethnic background? You seem to be blind to them. They don’t exist in your Black-White world.
