Mathematics, beyond the counting dollars level, is a game with symbols, so it is possible to refer to different number systems where 2 + 2 does equal 5. But “5” is redefined and is not what you would expect. Indeed, infinity can be added to the real numbers, in the extended real number system, which is a no-no for high school maths, but is used in measurement theory and advanced Lebesque integration. But, Leftist do not go to this level; instead:

“Some professors and activists argue 2+2 can sometimes equal 5, a controversial claim recently brought to light in a series of tweets that has sparked a robust debate among education watchdogs and others. The Twitter account Wokal Distance on Aug. 3 highlighted several screenshots amassed on the subject, noting: “This is a screenshot of people saying 2+2=5 … Among them are teachers, educators, and professors who plan on teaching this stuff to your children. So, let’s talk about what’s going on here, why they’re doing this, and how we can stop it.” In a message to The College Fix, the person running the Wokal Distance account declined to provide their identity or weigh in further on their thread, saying they would like their Twitter feed and profile to speak for itself. But the account clarifies that what the scholars are arguing is not that 2+2 does not equal 4, but rather “2+2 can sometimes equal 5.” The fundamental basis of the argument is that there is no universal answer to the math problem 2+2 that is true in all cases; they are not falsifying 2+2=4, they are deconstructing it, Wokal Distance argues. The Wokal Distance account goes on to explain that this deconstruction is effectively a destabilization of meaning. Under this so-called woke math, “2+2=5” because when a meaning is not fixed, lucid, and defined, that meaning can be redefined and warped. With this distortion, people can supposedly jump to any conclusion they desire.”
Of course, it is becoming popular to claim that mathematics is racist, which I covered previously, but here is more bs on this:

“Brooklyn College Professor of Math Education Laurie Rubel argued this week on Twitter that the mathematical equation 2+2=4 “reeks of white supremacist patriarchy.” Rubel’s tweet was retweeted and promoted by several academics at universities and colleges around the nation. According to a report by Campus Reform, Brooklyn College Professor Laurie Rubel, who teaches math education, tried to make the case this week that basic math is “white supremacist.” The tweets are part of a larger trend in recent scholarship by American academics, many of which have argued that “objective truth” is a social construct. “The idea that math (or data) is culturally neutral or in any way objective is a MYTH. I’m ready to move on with that understanding. Who’s coming with me?” Rubel wrote in a tweet. “Along with the ‘of course math is neutral because 2+2=4’ trope and the related (and creepy) ‘math is pure’ and ‘protect math.’ Reeks of white supremacist patriarchy,” Rubel added. “I’d rather think on nurturing people & protecting the planet (with math in service of them goals).” Several academics from institutions around the nation chimed in. Harvard Ph.D. candidate Kareem Carr suggested that math should be reevaluated because it was primarily developed by white men. “People say it’s subjectivism to ask if math is Western. I don’t get that. It’s an objective fact that some groups were more involved in the creation of modern math than others,” Carr said. “They may have been *trying* to make it objective but it’s not stupid to ask if they actually succeeded!” A few academics have pushed back. James Lindsay, one of the academics behind a series of hoax papers that were published in “social justice” journals, reminded Rubel and her peers that mathematical truths are objective. “It’s certainly the case, and the Woke need to be held firmly to the point, that feats of engineering like space travel and rocketry utterly depend upon accepting stable meanings of mathematical statements like 2+2=4 as objectively true, not mere accidents of culture,” Lindsay tweeted.”
That is true, but as a civilisation falls apart, these basic truths are lost, just as much of Greek mathematics was lost in the Dark Ages, and our new Dark Ages is rapidly approaching. And it goes on and on. So, there is nothing here about mathematics, or the foundations of logic, just ignorant people using their new politically correct weapon. In a sane society the deconstructionists would be silent, receiving the help they need, poor things.
