It all depends on what you mean by racism.
Here is the standard I hold, and I hold it in every direction without exception. Judging an individual by the category you have sorted them into, rather than by who they actually are, is the same error no matter which group is on the receiving end. It does not become acceptable when it is pointed at a group you find less sympathetic. It does not become acceptable when the people doing the pointing happen to be on your political side. The mechanism is identical regardless of which way it faces, and pretending otherwise is just the same categorical thinking wearing a different coat.
That standard has to apply everywhere or it is not a standard at all. Prejudice against Black people is prejudice. So is prejudice against white people. So is prejudice against men, against women, against Christians, against Muslims, against the working class, against older workers, against younger workers, against people with disabilities, against veterans, against people whose politics are the wrong politics, against people because of their body size or their accent or the fact that they once had trouble with the law. Every one of those runs the same program: take a category, attach a set of assumptions to it, and apply those assumptions to an individual before you know the first real thing about them. The individual disappears behind the label. That is the error. It does not get less wrong because the category is currently an acceptable target.
So when someone tells me it is fine to make sweeping, dismissive statements about an entire group of people because that group is fashionable to dislike at the moment, my answer is the same as it always is. Degrading an entire class of people based on the color of their skin is the definition of racism. It does not matter which skin, which class, which direction the contempt is flowing. The standard does not bend to fit the mood of the decade.
In the world I would want, we would judge each other by our behavior and our character. What a person does, what they have built, how they treat the people around them. The color of their skin, their religion, their culture, their politics, the group somebody else assigned them to before they ever opened their mouth, none of that would carry weight, because none of it tells you anything reliable about the individual standing in front of you. Those are the only things that should matter: what a person does and has done. Everything else is noise.
People Can Think What They Want
Here is where I part ways with a lot of people who agree with me up to this point. I am a strong believer in free expression. People can think what they want. They can hold ugly, mistaken, malicious beliefs, and in this country they can say them out loud, put them in a book, make a film about them. That freedom is not a flaw in the system. It is the system working.
The alternative, a government deciding which thoughts and words are permitted, is a far more dangerous thing than any individual bigot. There are countries that have decided to criminalize certain forms of expression, and however well-intentioned that sounds, it edges toward the thought police of George Orwell’s 1984. There are places in the world where saying the wrong thing about the government can get you arrested or executed. I would rather live in a country where someone is free to say something repugnant than in one where an official decides what I am allowed to say. Freedom of speech, freedom of the press, freedom of expression. These protect the speech you hate, because that is the only speech that ever actually needs protecting. Nobody tries to ban the popular opinion.
The good news is that you are not required to listen. You do not have to read the racist newsletter, watch the channel that infuriates you, or give your attention to anyone whose entire project is putting other people down. You can simply turn them off and point your energy somewhere better. Freedom of speech has never meant a right to your audience.
The Cost Nobody Counts
And that is the part I actually care about, because it is the practical truth sitting underneath the moral one. Every time prejudice stops you from engaging with a person you have already pre-judged and dismissed, you lose something. Sometimes something small. Sometimes something enormous. A friendship. A perspective you could not have gotten any other way. A person who would have made your world bigger and more interesting than it was before you wrote them off.
That is the real cost, and it is mostly invisible to the person paying it. The category does its work silently. You never meet the people you have already decided not to meet, so you never find out what they would have been to you. The loss does not announce itself. It just quietly makes your world smaller, one avoided person at a time, and you go through life assuming the smallness was simply how things were.
So instead of spending your life cataloguing who is being prejudiced toward whom, spend it on the people who are doing good, building things, and helping others. Challenge bad ideas with facts when the conversation is worth having. Learn the difference between rhetoric and evidence. Understand what a logical fallacy actually is. And when someone is not willing to have an honest, fact-based conversation, stop spending your energy on them and move on to people who are good for you, good for your family, good for your community. If you focus on the positive, you will tend to see the world in a more positive light, and you will tend to do more good in it.
The Real Question
So, to actually answer the question, “why do some people think racism is okay?” The honest answer is that almost everybody draws the line somewhere, and a great many people draw it conveniently. They condemn the prejudice that points at groups they like and excuse the prejudice that points at groups they do not. They have simply decided that their preferred direction of bias is the righteous one. That is not a principle. It is a preference dressed up as a principle.
The harder, more consistent position is to apply one standard everywhere and judge people as individuals, full stop, no exceptions for the directions that happen to be socially acceptable at the moment. It costs you the comfort of an easy enemy. It gives you back a much larger world. I think that is a trade worth making, and I have spent a good part of my life making it.
I write about all of this at length in my forthcoming book, Everybody’s Prejudiced: How We Judge, Why We Do It, and What Rational People Choose to Do About It. Coming soon.
