Well, this conversation has taken an interesting turn. I'm arguing against racial supremacy with an anti-racist who doesn't support it anyway.
You are obviously ignoring the whole point about there being the hugely possible scientific or empirical evidence for justifying racial prejudice. It matters little for this possibility if there is also a cultural and educational causation. If there are genetic differences then there are genetic differences, and there will also be cultural differences. IOW, one does not deny the other.
I say the possibility is huge, for I really do not believe that if one suss this whole shenanigan out between various ethnicities we won't find *any* difference whatsoever. That would be a miracle by itself, perhaps. I have little idea, but it matters little to me. The reason why is that my anti-racism does not stem from these empirical observations, but from my values.
Obviously, different races and ethnic groups are not completely identical in every way imaginable. I can accept that and still oppose racial supremacy and hierarchies.
I previously said that I am not using racism in its broadest sense because, technically, if you stretch it far enough, the belief that black people have black skin and whites have white skin could be considered racist. This is hardly important for most discussions, which is why I am speaking of bigotry and supremacy.
While they vary in appearance, whites, blacks, and Asians are all capable of the same achievements. They have displayed a wide range of values and attitudes. Individuals and groups of whites can resemble individuals and groups of blacks more than other groups and individuals of whites. The Caucasian world has historically been as barbaric as any other, and not always the most advanced, particularly in terms of moral development. These facts alone justify my position.
I oppose all forms of racial bigotry, institutionalized racism, and the vast majority of stereotypes because I believe they are immoral. However, I also find them extremely lacking in logic, and I think it is important to point that out.
When people shift the conversation from values to observations, then you are already losing the war and that's precisely why you say that some times it appears to you that "white supremacists" seem to win the argument: because you are valuing more this "factual" war than the war about values. If you deny them that territory is even arguable, then they lose by fiat. And this is not "whimsical" at all. That's nonsense. We have long established egalitarianism and non-racism as core values of our societies and calling them "emotions" or "fads" or other shenanigan is just ignorant waffle. Might as well call "liberty" or "democracy" as "emotional arguments" or whatever.
No, they sometimes seem to win the argument because no one in the room has enough information to counter their bull****. My opposition to them is part moral and part logical, for all the reasons I have outlined. I am not "losing the war" by daring to fight these ideas from more than one perspective.
Unfortunately, many people will still resort to lazy stereotyping as a means of classifying others. Any method that does not combat this is, at the very least, disadvantaged. It will have a harder time defeating institutionalized racism, which feeds off these stereotypes.
Emotional arguments can serve a useful purpose, and form the basis of any moral system. However, when you can bolster them with logic, it is best to do so. Does the statement "women are be just as smart as men" weaken arguments for gender equality?
