I hear authors mention it sometimes. But, I don't see the examples or evidence.

Maybe I'm just not on the math departments enough.

Eh. If you can read Hestenes or the Cambridge papers without some red flags going off, then this is just a subjective thing you're not gonna understand and we'd best not try to litigate it :p

(more extreme examples can be found on the heaps of GA-based papers, youtube videos, and comment sections around the internet, but I think the original papers do contain some of the concerning stuff on their own)
