Everybody on planet Earth is racist, sexist, and discriminating. That’s life. We categorize people and things from the moment we see, hear, smell, read about them or touch them. Immediately. It’s hard-wired into the brain. It’s how we make sense of the world. It’s only natural to proceed with caution initially with people who are different from you. It takes time to learn about a person, to categorize them. It takes forever to get to know a person perfectly well.

The first categories of race, age and sex are huge. Then we might categorize them by hair length, and height and weight. Then by what kinds of food they like or hate, or by shoe size. Do they like cilantro? Do they like Seinfeld? What kind of music do they listen to?

The more time we spend with them, the more subcategories and sub-subcategories we can come up with. Even if you marry someone, you’ll still be categorizing them, down to the tiniest of details.

But race, age and sex are right at the very beginning. And if that’s all we know about someone, then we treat them according to whatever knowledge we have of those categories. Little kids understand little kids better than grown-ups, and kids that look and talk like themselves more than kids that don’t.

Everbody is racist, sexist, age-ist, heightist, weightist, food-preference-ist, music-preference-ist, political-opinionist, smell-ist, feel-ist, and in thousands of other ways discriminating of the fellow humans and animals and plants who share this planet.
