Political Nihilism has never achieved anything and offers nothing to anyone. Likewise a "ruthless critique of everything existing" only achieves political inertia and smug satisfaction in armchair theorists as the world around them falls apart. How comfortable it is to criticise everyone else for trying to make the world a better place in which we find it, and how paralysing it must be to be afraid of having the same done to you. If you're not making mistakes you're not making anything.
Personally, I find La-Z-Boys to be overrated
@cocoron It kinda has a positive history in russia, but that may not be the same definition of nihilism.
Sunbeam City is a Libertarian Socialist solarpunk instance. It is ran democratically by a cooperative of like-minded individuals.
