His whole work, a pamphlet discussing massacring the bourgeoisie

It's not cool to make stuff up just to win an argument. It makes you lose the argument.

In fact it was a part of Marx's work in much the same way as you are arguing it here: he was falsely accusing capitalist and bourgeoisie of mass surveillance, even while he was trying to do it himself. But yeah, Marx is Marx.

Yeah, Marx was trying to establish a vast spy network of ravens and pigeons, spanning the whole continent on Wakanda. /s

Both mine and your statements are equally true.

Yes, the need for mass surveillance of the masses is actually in Marx and Engels's work.

Yeah, in the unpublished archives that only you have access to. /s
