Any word can be used in a derogatory fashion. I'd say the non-binary community knows this better than anyone.

Like the word "Gay" has been used in a quite derogatory fashion for many years now. It's original meaning, the people it's being used to refer to and how it's being used are, objectively, three very different things.

Deeming singular words as slurs or hate-speech, in and of themselves, is by far the most idiosyncratic way to get around an actual problem. I'd say the 'Intent' behind it matters more. And the 'Why' of it all.

Regardless, I don't think dear old Elon is in a position to call-out anyone for anything at this point in time.
