The whole concept of an "echo chamber" is fucking idiotic. If I've joined a place to discuss specific things then I want to discuss those things, not get every single topic derailed by a bunch of idiot trolls. The people crying about echo chambers are literally only there to gaslight others into believing their concerns are unreasonable and fringe. More often than not; people benefitting from or brainwashed by the status quo telling marginalized people that their demands for being treated like fucking humans is somehow absurd. Fuck outta here with that shit if you've ever done that in any way, shape or form. You were brought up wrong and you should be ashamed of yourself.
It's a loaded phrase. It has an intended meaning, to guilt people into the free speech trap. It's used by the alt-right, and while the understanding of it might be up for debate, I ignore people that use the term. As if acknowledging that a forum doesn't tolerate intolerance is somehow bad because of "echo chamber".
Meanwhile every single nazi forum instantly bans any expression of dissent. None of the people using that phrase care the slightest about free speech, having opinions challenged or frankly anything of value. They are nihilists and should be treated as such (and that's coming from someone who doesn't even have a problem with nihilism, just don't expect to be taken seriously in debates.)
Usually that's what you think of when you think about echo chamber, a single dominant viewpoint expressed.
To me, this comes across like a crock of shit to be honest. Rarely do I get more than two or three people agreeing with anything I say in an opinion-based discussion thread. I am challenged constantly and sometimes there's even a level of verbal hostility involved. So please, tell me how that makes any sense with your claim of there being a "single dominant viewpoint expressed"? The only way you can rationalize that is if you equate everyone who is not a racist piece of shit with being a "liberal" or whatever.
Newsflash: I consider liberals to be extreme right wing and barely identify with ANY of their opinions. I'm just also not a fucking nazi because those aren't the only two options or opinions to express in a discussion. If you complain about a forum being an "echo chamber" because people actively perpetuation oppression of minorities aren't welcome, you have an insanely narrow view of what diversity of opinion means. The current wave of US Conservatives are a complete joke and would have been treated as such (and arguably are) globally if it weren't for the US voting system being a steaming pile of trash.
So no, there's not a single dominant viewpoint being expressed. There's just a completely useless branch of idiocy that has no place in society being treated the way it should be. If you have economically conservative ideas – no one is going to silence you on this forum. If you extend that concept to human rights? You and me are gonna have a problem every single day of every single week, no matter what you call yourself. Liberal, conservative, class reductionist commie – I don't care.
