There is a difference between disagreeing with someone, and someone being an idiot/crazy.
You can disagree with AOC's goals, the green new deal, her thoughts on police reform, etc, but that is a disagreement on policy and world view, not a matter of sanity or intelligence.
MTG is a fucking stupid nut job. AOC isn't the left's MTG.
When you show up at someone's office with 2 other retards to yell through a mail slot about the 'wrath of god coming down on our nation', there is no reasoning or discussing that sort of stupidity.
I don't agree with everything AOC says, but comparing her to MTG is asinine. She has many of the exact same beliefs and goals as Bernie Sanders and other leaders around the world, are they all stupid too?
