I heard a friend who had a brilliant theory. The rise of ad profiling from Facebook and Google etc, has bleed into the public consciousness at large and now it's considered normal to categorize people by race, gender, politics, and income etc.
First the companies did, and now we all do.
But of course, a person is more than their race, or gender, or income, etc. Most of the time they have very little in common with those groups aside from color of skin, reproductive organs, or money in the bank.
It's just how the advertisers see us.
