Straw man: (noun) An intentionally misrepresented proposition that is set up because it is easier to defeat than an opponent’s real argument.
(Did you get that? It’ll be on the test later.)
I keep running into variations on this particular straw man argument: ‘You think perfect grammar is all that matters in a book and that plot and characters are irrelevant!’ Um… No. Grammar enthusiasts do not believe (or say) grammar is the only thing that matters when writing a novel, and claiming that we do is ridiculous. We just want whatever we’re interested in reading to be, y’know, readable. Why is that such a problem for some people?
In reality, this second picture is a much more accurate (metaphorical) depiction of a “grammar ninja” (cleverly disguised as a lawn gnome — we’re sneaky that way) and what such a person believes.
