wAIT a fucking minute.... You can't use that word "racist". It comes from race. What the fuck are you gonna call a racist now?
That's a huge
non sequitur. Denying the validity of a concept does not mean that one cannot use it within the context of people who believe in it.
Do you think that people who don't believe in God should not refer to people who do as "theists"?
As for your attempt at analogizing between race and stature - people are, objectively, shorter or taller than other people. People are also, objectively, darker or lighter skinned than other people. If short people tend to be worse at math (which I just came up with off the top of my head as an example; I have no idea if it's statistically true or not), most people would consider it absurd to posit that the same biological trait which causes their shortness also causes their relative mathematical ineptitude.
So why should it not be just as absurd to conflate correlation and causality when it comes to skin color and, say, intelligence? Considering that when you put members of the same race in different social and cultural environments their relative intelligence differs widely, does it not make more sense to take the position that it is culture, rather than genetic heritage, which causes intellectual disparities between peoples?
For example, equatorial climates lead to a condition in which less ingenuity is required for people to survive. As a result, the emerging culture will value ingenuity less highly than, say, people who live in a tundra. But if, after many generations, you put an equatorial people into a tundra, you will immediately see latent intellectual capacity begin to emerge. Likewise if you put Steppe peoples into an idyllic tropical paradise, you will see a culture emerge where less emphasis is placed on inventiveness and cunning than that which had previously existed.
Equatorial climates also produce darker skin pigmentation, so you tend to find that people with darker skin colors have cultures which value intellect less highly than other people. That's a correlation. It is not a causal relationship. It is not evident at all that the same genetic history which produced the dark skin also produced the values system of the culture. In fact, what caused BOTH the culture and the biology to exist is the Sun's effect on the environment where they lived. The effects share a common cause; their relationship to one another is parallel - purely correlative.
The theory of race does far more than acknowledge the objective physical differences between different peoples (in fact it cannot properly acknowledge those difference in the first place, since racial theory makes qualitative statements, and those differences are quantitative rather than qualitative). It attempts to explain
cultural differences by ignoring testable environmental explanations in favor of biological ones which are, at this point in time, untestable.
