Not Lemmy specific. There was US legislation related to the word being deemed offensive fifteen years ago (given the slow nature of Congress, it wasn’t a new sentiment then, either): https://en.m.wikipedia.org/wiki/Rosa’s_Law

Fair enough that plenty of insulting words could be cast as abelist: but my guess is that a word like “idiot” is old enough that most folks called that in a medical context aren’t around any more. Maybe I’m wrong though: plenty of folks do push against saying things like “crazy” in an insulting manner.

Him not being the Spock we know is kind of the point though, right?

He was a little messier before he got himself together. His human side maybe is less bound by Pon Farr rules, and he’s not yet the hyper competent officer we love in his later years.

He screws up and then that becomes a motivating reason to control himself is pretty compelling, to me at least. He did go a little buck wild helping out Pike in TOS, so he’s certainly still got a wild streak in him.
