I know this is the Onion but the left is inherently anti-authoritarian and advocate of horizontal structure of society with no top-down leadership. Of course we'd be disorganised 😂 Case in point, this and the hodge podge of left wingers in the Spanish Civil War ranging from communist, social democrats, democratic socialists to anarcho-syndicalists. Spanish leftists even attacked each other. The Democrats also don't even get along and this is why Republicans under Trump is gaining more headway.
I'm proud that we're maverick, but this also leads to our characteristic factionalism and thus easier to be disrupted and destroy.
