All but one of the examples you listed aren't really necessarily true though. Like I said, they are all just stereotypes.
You said, quote:
there are racial supremacists that aren't fringe?
What exactly qualifies as non-fringe racial supremacy?
So I responded with examples of non-fringe beliefs about racial superiority.
This isn't about steel and cotton, because the only one that is similar is the first dog comparison. Because that is the fact in the bunch.
Also, I don't understand how the KKKs feelings on basketball mean anything.
The point is that "superiority" is too vague to mean anything without context. Any time you ask "which is better" you need
context to be able to answer the question. A "supremacist" doesn't necessarily believe that one thing is always and in all things better than something or someone else. They believe that it's better in the contexts
that they care about.
It doesn't make sense to say that steel is better than cotton or cotton is better than steel. It does make sense to say that steel is better than cotton...for building bridges. It doesn't make sense to say that chihuahuas are better than siberian huskies. It does make sense to say that if you're an 80 year old grandmother with broken hip who wants a lapdog, that the chihuahua is the better choice.
Similarly, you can say that if you want a good basketball player, a black guy is more likely to be the superior choice than
an asian. And even a KKK member would probably agree with that. Being a "racial supremacist" doesn't mean that you believe that one race is
always better. Only that it's better in the specific cases that you care about.
And with that understanding, there are
many socially acceptable "non fringe" beliefs about racial superiority. Some of those beliefs might be true. Some of them might not be. And there might not be an exact one-to-one correlation between accuracy of those beliefs and how socially acceptable they are.
Nevertheless, entirely mainstream non-fringe beliefs about racial superiority do exist.
Again, if you say "asians are good at math" in a public place you don't generally get shot or accused of being a fringe weirdo for it.
