In all seriousness I feel like the common answers I saw of Diogenes (because that was like, his entire shtick) or Socrates (because they killed him for being annoying) are probably better answers but saying its Trotsky on a leftist forum is way funnier.
There was 80 judges who declared him innocent but demanded death penalty for him anyway lol.
Truly the most annoying correct person ever.
Wouldn't that be Lenin?
Nah Lenin was funny af. You get away with being as catty as he was by being funny while you do it. Socrates missed this trick and was killed for being an annoying shit.
