This has been the message of the Left for over a century, and always ends in rivers of blood.
Russia's mass starvations, Russia's mass purges, China's mass starvations, China's Cultural purges, Cambodia's Killing Fields... East Germany, Romania, Korea, Bulgaria, Vietnam, Hungary, Ethiopia... 'Twas ever thus.
(And yet the MSM's thought-control program has been so effective that their opponents are seen as the hate-filled purveyors of death. Stunning.)
The consistent message from totalitarian collectivists of all stripes has been simple and consistent:
Human beings are things, animals or machines.
Ergo, you have no right to live.
All of the slaughter, atrocity and horror of the last century flows directly form those premises.
