I mean it isn’t exactly nitpicking, is it? Sure, we don’t tend to care that much about protists vs algae vs bacteria vs anything else that is tiny in common parlance, but these things are all VERY different from each other, aren’t they? Like, different kingdoms different? I mean, if someone ran around saying that rabbits were a form of reptile I wouldn’t think you were nitpicking for correcting them as being a mammal.
