You're the only one who needs it explained to you. Even after it is, you're still too fuckin retarded to understand that it's an insidious philosophy that has impoverished, oppressed and murdered hundreds of millions of people. In the few remaining countries that actually practice it in whatever degree people live in squalid shitholes, they're subjected tyranny, while the governing class is a bloated oligarchy.
When people joke about stupid people being dropped on their heads as babies they should have met you first, because someone obviously spiked your dumbass like a football and kicked you for a 30 yard field goal that hit the post. Fuckin imbecile.
