One of the more unusual elements to questions like these is how often the participants deny the already-is and act like we are debating the ought-to-be. Racism isn't nearly so strongly the position of white nationalists so much as the air we all breathe and the fashion in which the world functions. China is for the Chinese and is wildly racist against dark-skinned people, for example. Look at India. When other posters comment something like "we seem to exist in society fine", this observation to large extent discounts how little we coexist at all. Dark-skinned people are and have always been heavily segregated from lighter skinned people. People cite absurd exceptions like the occasional time and place or circumstance, like Barack Obama, or some quantity of multicultural aristocrats existing during the Roman Empire, but the bulk of ethnicities in the world are segregated. Black people in the United States lost half their wealth in the financial crash of 2008-2009, and barely anyone discussed it. There is a heavy amount of normalization going on constantly within race itself: black people didn't talk about it, either, and they didn't bring consequences upon the Democratic party.

People like Jared Taylor both are and aren't excessive, unnatural freaks, depending on your philosophical position. They are people who awkwardly speak out loud what everyone is thinking, and take the fact that everyone is thinking the same thing to an even more excessive and immoral position. Like most outcasts and extremists, Jared Taylor uses everyone's alienation from their own thought as a justification or solution for his own alienation and malcontent. In other words, his argument is sound but his position isn't. And society's reaction is much like a public debate on spanking: everyone did it and probably it was dealt with as a fairly ordinary thing for all of human history (lightly abusing children, that is), but because we fear abusing children so broadly, the subject is spoken of in hushed tones and with terror or approbation.

Why? Well, it's just how we're built. This is how we view morality, we abuse the abuse, we run from the category itself. We abolished child labor, and we have no great cogent argument for why adults should do the same nightmarish jobs we protect children from, nor why adults and children are OK to take those jobs overseas from us; nevertheless, we cannot speak rationally about the subject. Children can and do participate in labor when the need is there. Yet naturally we are obsessed with them as a receptacle of our goodness. And now, as our divorce rates are high and we have less children, we tell ourselves we figured it all out morally, because we don't now allow 14 year olds to have children or "serious relationships". So it goes with race: we want to be Good, so we want racism not to exist, and we mistake that argument for Not Being Racist. Someone like Jared Taylor disturbs people by basically inverting that position, concluding something bizarre like Racism Definitely Exists and Endures, So It Must Be Important.

What in the hell is my point? Basically, if you want to do better philosophy, stop talking and thinking about racism like it's this weird proposal placed freshly on the table and start recognizing how ubiquitous and successful it always is as an underlying framework for the world already. Racism cannot be "justified" - it is one of the pillars of our very existence. Racism needing justification is a statement as unusual as suggesting sex needs justification. Like sex, racism is something which, under various circumstances and to varying degrees, quite simply is.

Have you ever read that traffic jams are caused by an additional 10-20% of traffic, not by what we suspect, which is something more like a 200% increase? It's just the additional fractional amount which slows everything down. I think of racist ideologues the same way. Their position is generally something like 10% more racist than everyone else's. Which is why they are the thermometer reading of a constant ongoing problem (civilization and resource management and encroaching threats of ethnic/nationalist war) much more than they are "wrong" or "insane".

The cure for racism isn't anti-racism. The cure is having enough abundance to allow people to pretend racism doesn't exist.
