Truth is not an echo chamber, accepting other people who aren't hurting anyone just by existing isn't an echo chamber, kindness isn't an echo chamber.

I don't need to consider "alternate beliefs" that are just lies. There's this idea that if I'm not constantly reading stuff by straight up Nazis, that I won't understand that they are Nazis. Not having to read nonsense as possible facts is one of the really cool things about having critical thinking skills.

The idea that Mastodon is an echo chamber is crazy anyway. I am more informed here than I ever was on Twitter. People rarely just state opinions, they back them up, and as a frequent poster, I promise you that if you do post something without a link to back it up, someone will ask for one.
@RickiTarr I think... we are an echo chamber of verifiable information, then. Anything we put out here circulates, reinforcing the principles we hold high, but ultimately stays in our bubble (because it's not received from outside the bubble). So, technically, that is an echo chamber, too, unless our definitions of echo chamber differ.
@anathem In my mind, it means only hearing ideas you agree with, and I'm certainly not, but maybe some are. I think it involves some degree of propaganda, like how Fox News twists every story to praise their glorious leader to the point that a good amount of it is straight up lies. On Mastodon, I don't feel like I only hear ideas that are the same as mine, I've had plenty of debates here, but on the basics like Civil Rights, people need to agree or yeah, really easy block. Some things just shouldn't be up for debate. Mastodon has a larger population for whom basic civil liberties is just where we start, those are values we share, and an expectation for everyone. I don't need to have a debate on who deserves rights and respect, because someone who does, doesn't deserve my respect, let alone a platform that I follow.

@RickiTarr So, in your definition, "echo chamber" necessarily includes "evil propaganda"; while my definition is the dry technical view of the ideas' flow and the social dynamics that are involved?

They already perverted the Truth. If they subscribe to your definition of echo chamber, and I assume they do: by insinuating that we're an echo chamber they're effectively reinforcing the scientific method (among other topics, I just picked an example) as "evil propaganda" now.

@anathem Propaganda is always evil, it is in it's nature misleading. An echo chamber assumes you only hear views you agree with, or already know, I don't, I hear more ideas than I ever have here.

@RickiTarr And yet, we are here because we want to hear that multitude of ideas, backed by verifiable sources. Which is in itself contrary to the authoritarian mindset, so they call it leftist-libertarian propaganda.

Which means, assuming your associations with echo chambers are shared by most people, those who call us an echo chamber are reinforcing the notion of us as propagandists.

Which validates your original post in my opinion: We have all reason to be agitated about us being called an echo chamber.
