Babe, the reaction you are criticizing is a very common reaction to the kind of wording that the author chose to use in his title. The author should have expected and anticipated that reaction.

If someone words a title the way the author did and does not expect that kind of reaction, then that person needs to get around more.

If you criticize “white people” then it is obvious that “white people” will defend themselves. It is futile to expect anything different.

The article would have been equally effective without the gratuitous reference to “white people” and the author could have saved himself the effort involved with his feeble attempt to offer an “explanation.”
