Isn't that an oxymoron? I'm not sure it's possible to have "incisive stupidity" or "biting and caustic stupidity".
Yes, precisely. Although we can qualify that a bit... some here are not necessarily stupid and delusional, but seem to take immense pleasure in baiting. Others are not stupid, but do qualify as delusional and baiting. And then there are a special few that exemplify all three characteristics... and appear so much like the hard left it's nauseating.
