We're all fighting for basically the same thing. Various flavours, but essentially the same. I personally wouldn't betray the revolution should it come.
1000% agree, we need to collectively get our shit together, get over the little differences between what our end goals are, that can be sorted out later, and anyone who isn't a fucking fascist would be willing to see other collectives have their own system and still work in harmony.

I wonder if part of it is that climate change might mean the death of modern human civilization, so could the slim hope of life as a slave seem more preferable than the greater certainty of death as a free agent?

I cannot fathom that, but then again that's why I am on the Fediverse rather than on Reddit. :-P
