Earlier quoted context omitted.
If QAnon is truly "pretty common" on HN, then I'm sure you could easily point out, say, 3-4 QAnon posts on here from the past week. That should be easy if QAnon is common on HN, right?
I specifically said (Trump|QAnon). It's pretty hard to tell the average trump supporter apart from the average QAnon supporter. And you could look at my comments and those who commented in return to find your 3-4 posters. That's pretty easy, right?
Don't believe me? Go read thedonald.win. After you recover from the shock of realizing that many of them are planning/hoping for another assault on democracy on the 17th, you'll see that the attitude toward QAnon is not one of approval .
And I've never seen a QAnon-related or -influenced post on HN. Clearly, there are Trump supporters, although they're a very small minority here.
So yes, (Trump|QAnon) evaluates true on HN, but only because of the first term in the expression.
