How to people exist to the age of this woman, without anyone telling them they are batshit crazy? This person (presumably) went to school at some point, some reasonable adult, like maybe her doctor, should have mentioned that it's... Oh, why do I bother, the Boomers and Millennials have destroyed rationality.
Do not underestimate the power of "new math." When you learn 2-3 ways to solve mathematical equations, you learn order of operation matters, you learn how to 'solve' things logically, and think about what your saying and doing. Then comes "do it this way or it's wrong" math, which just broke the fundamental building blocks of logic and created mindless obedient sheeple.
I blame math more than the boomers white lies. Boomers, well, I'm glad my immediate family skipped a generation. My father was born in the 20s (greatest generation, so it's called), I am GenX and I remember those people clearly, they were not "flower children" hippies of the boomer generation... And "reasoned thought" was still valued when they were being raised (to some extent, but that whole New Deal bullshit propaganda seemed to stick, hard to tell anyone post-war (WWII) that "oh, btw, all that shit we told you, pretend it didn't happen, k?" (and there was shit, I've heard some WWII stories that... it wasn't "glorious," it was horrid).
In the end, I still think "new math" shit broke them more than anything, they can't even realize it's "Truth, Justice, and .." They get order of operations wrong, it's "justice" then "truth" later if it's convenient (for example, the last 2 years of BLM riot shit).
