How can you expect yourself to integrate well into any conversation when you’re fixated on “well technically…”
If 99% of people colloquially agree that A = B, then it doesn’t really matter if ‘A’ and ‘B’ are really the same thing if everybody knows what we’re talking about. It’s the most obnoxious shit when someone tries to argue in this way, and you’re not convincing anybody or adding anything meaningful to the discussion.
For this specifically, “Traitorous Critic Fallacy”. More broadly, an Ad Hominem argument.
