Because when someone makes the argument that "ok now discrimination has gotten out of hand" it usually is implied "... Now that I'm the target!" Which would imply the author isn't used to being the target of discrimination, which would imply middle aged white male.

The point I was trying to jokingly bring up is a valid one, I think. How much of what we do leaks identity-related metadata? How much are of the responses we get are responses to that inferred metadata?
