>one's chosen enemies must be simultaneously terrifyingly powerful and incompetent dunces
I've got some bad news for you.
At first I thought you were referring to Umberto Eco's laws of fascism: "Fascist societies rhetorically cast their enemies as at the same time too strong and too weak."
but it's subtly different, because incompetence is not weakness.
I really don't find it coherent to call someone who you keep consistently losing to stupid.
