Real life is the biggest echo chamber you’ll ever find. Online is one of the most diverse spaces you’ll find. That said there’s nothing to be gained by humoring fascists, ML, or groups only interested in engaging in bad faith. I say this as someone who trends social libertarian and is always up for some Marxism.
I do think real life can be an echo chamber, but if you have a diverse range of people you interact with, it can be not an echo chamber at all. Having multiple friend groups, attending social events, etc can make real life more diverse.
(Ofc there’s things like living in a first world country making an echo chamber of people that don’t care about third world issues, but that’s beside the point)
Online is also the same in my opinion.
Then yes, we want an echo chamber. Happy? You’re still defending scum, no matter the semantics.
Step 1: Don’t engage them, no room for their rhetoric.
You are to fuck off, and take your crypto and your blue line flags with you on the way out.
