I’ve never been a big fan of depopulation. It doesn’t make me sit up and think, this is the way to go. I assume you aren’t in favor of it, either. Most people don’t like it.
Even anarchists can see a plan to wipe out large numbers of people might come around and tap them on the shoulder. Self-absorbed nihilists with no moral compass whatsoever do retain an urge to survive.
(Bill Gates and Rockefeller technocrats don’t count. They aren’t anarchists. They want to build on the ashes of what they destroy.)
