> Dimwit and midwit mean two different things.
> Midwit is an internet slang term, often used pejoratively, to describe a person with average or slightly above-average intelligence who believes they are exceptionally intelligent or insightful.
Does this not describe most of the people on this forum? Why would you invite such comparisons if you aren't confident you're better or "more correct" in some way? It seems they intended to use "dimwit", as that would result in comment making more sense overall by drawing a clear contrast with the speaker.
One commonly observed midwit behaviour is to make arguments based on the dictionary definition of a word, having failed to understand that there is a complex set of cultural and social connotations implied by its use. In the case of the midwit, the implication is that intelligent people understand, stupid people understand, but the half-smart get completely the wrong end of the stick.
