The worst governments. The less intelligent, and, therefore, the less enlightened, leaders of governments still have not renounced slaughter as a way to keep people off the streets. They are not, themselves, bright enough to understand that the best way to maintain themselves in power is to provide little spaces of freedom on their well-controlled streets. Those like the Castros, Mugabe, Stalin, and other murderous tyrants are so overwhelmed by vanity that they would rather die than lose even that tiny bit of power.
The perfect example of how hate-filled leftists destroy themselves with the death they love occurred when Jim Jones had 900 of his followers take themselves completely off the street when he thought his tiny government was threatened.
