What was the defining aspect of Stalin? Socialism? Wrong. Socialism is a system and for him, a tool. Instead the defining element is who he was, that is, a self-obsessed, heartless individual who regarded others as tools, means to ends, specifically, his ends.
Manipulating the system, any system, to gain for oneself regardless of how it harms others? Sound familiar? Yep, that's Applied Goblinism for you.
All systems can be abused and twisted, so we must not let down our guard, because that is when the sociopaths come out. The ecoterrorist, the Taliban, the goblin, none of them care about you, only their fanatical beliefs, and whether that is worship of nature, Allah, or their own egos, the unifying element is a belief that humanity has no value by itself.
