Is it racist to say 2 + 2 = 4?
California and Canada both seem to have more than their usual share of nut jobs. Teachers from both places have declared it is racist to say 2 plus 2 equals 4. If you dig in a little bit, you will find that their beef is not with that equation per se, but it is with math being called "neutral" and "objective". They point out that whites dominated math development with not enough representation from blacks and others. So they associate "white supremacy" with math.
I don't know who is to blame for lack of "equity" in math development. White man ruled a lot of the world for a time, but didn't blacks have most of Africa to themselves all the time? Why didn't they develop math in Africa? China is another place that is untouched by white man. Indians apparently had a head start in math, but they squandered it by working on religion, philosophy, and arts instead of focusing on "capital generating" fields like math and science.
How would an increased "equity" in math development have affected math? Libs complain about the mentality that there is only one correct answer. But for many math problems, there really is only one right answer. Would the increased participation of blacks in math have changed this? Think about it because we have a problem here. Math also "works" in the real world in an objective sense. We have a few centuries' worth of experience to back this. What that means is, if there is a new math from blacks, and if it contradicts the current body of math knowledge, the new math - the "black math" - wouldn't work in the real world. So, it follows that no matter who worked on developing math, it would have only turned out the one way.
So the libs are bitching about math for no good reason. The equity argument is fallacious. We know libs love relativism. Math is so absolute and so objective and so final. May be that's what annoys the libs about math. The sciences are similar to math in this aspect. They don't need subjective approval of people. Anyone with the right resources can verify and reproduce experimental results. And if that proves to be a problem, the original experiment is considered invalid. ("Climate Science" is exempt from this. "Climate Science" appears to be completely untethered from reality. Many people think "Climate Science" is a gigantic fraud.)
We see libs fight with biology all the time. I am going by Twitter biologists here, but the difference between male and female is as final and definitive as it gets. For reproduction, male humans produce sperm, which is tiny. Female humans produce eggs, which are relatively gigantic. There's no spectrum of sizes - tiny and gigantic are the only two sizes. There are no little-bit-female-little-bit-male people. You are male, or you are female. "Gender fluid" is a thinking defect. But the libs seem to find the dichotomy oppressive.
There are a few other things that libs find oppressive: English grammar, punctuality, efficiency, result-orientedness, objectivity, and a few other things that people adopt for achieving success in professional life. Libs ascribe all of these things to white culture, which implies that blacks are lazy and sloppy and illiterate when left to their own devices. It's like the white man has imposed a bunch of oppressive rules on the blacks. The whites follow these same rules too, though, right? But the blacks suffered from slavery. They ought to get a pass. Isn't that right, libs? :-)
