You can literally go on Facebook and find somebody spewing "you're racist". They may or may not think "I'm racist too, but I handle it better." For some reason they usually are careful not to say anything pointing to that direction. We can't know that those people think.

That racist stuff on twitter could be just humor and nothing more. We don't know how those people think either.

The point of the article was "hey people, you might be biased in this way." Now what's wrong with saying that aloud?
