Which is why I clarified "and not working towards a degree anymore".

> Find a few people in PhD programs in the US and tell them you don't think they're in academia

I have a lot more experience interacting with PhD students than you seem to assume, and I can assure you that one of the most worn out conversation topics is whether they should go into academia after graduation. We can nitpick what that says about whether they are currently in there, but that's pointless. The parent was implying that the prototypical image of someone who is 'in academia' is a PhD student, which is definitely not the case. The way the term is usually used, the prototypical instance of someone who is 'in academia' is a faculty member (tenured or not).

Edit: check out the description here if you don't believe me: https://www.findaphd.com/guides/working-in-academia they take a somewhat broader stance than me above, but they make it clear too that academia starts after the PhD.

This seems very tied to the specific phrase "working in academia" which you appear to have introduced. Would you argue that grad students aren't academics?

Of course not - being an academic means working in academia. In the English-speaking world at least, in other parts it may mean other things (eg people who have an academic degree, regardless of what they do now).

They are training to be academics
