The slippery slope from non-vegetarianism to cannibalism
According to spiritual communism, all properties on the surface of the globe belong to the Supreme Personality of Godhead. The population has a right to use goods only after offering them to the Supreme Personality of Godhead. This is the process of accepting prasada. Unless one eats prasada, he is certainly a thief. It is the duty of governors and kings to punish such thieves and maintain the world nicely. If this is not done, grains will no longer be produced, and people will simply starve. Indeed, not only will people be obliged to eat less, but they will kill one another and eat each other’s flesh. They are already killing animals for flesh, so when there will no longer be grains, vegetables and fruits, they will kill their own sons and fathers and eat their flesh for sustenance.
