Do they genuinely believe the shit they’re peddling or are they paid propagandists or is their something more nefarious afoot.
From my interactions, I’ve come to the conclusion that they’re mostly seriously broken people who’ve discovered Marx, convinced themselves that capitalism is the cause of all suffering and believe socialism is the solution that will free them from their trauma. The degree of their attachment to socialism is a reflection of the degree of their suffering and brokenness.
If they weren’t so toxic, they’d be deserving of compassion and forebearance.
