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 were multiple Cato’s and every one of them was a self righteous patrician traditionalist.
I’m referring to Cato the younger, contemporary of Julius Caesar who is probably the more famous one but there’s also Cato the elder who was basically the same figure a century beforehand.
But it doesn’t matter which. Misogynistic patriarchal patricians who believed that their position atop the socio-economic hierarchy was a law of nature.
