It's funny how people think both this and states 4chan has always been rightwing since 2000s. The truth is your political bias says nothing about your intelligence. Stating otherwise just looks like boosting one's ego to me.
Also the reason you don't see right wing opinions on Lemmy is probably by and large because the right wing instances are being defederated by larger left-leaning Lemmy instances. Not saying if thats wrong, but that's just how it is.
I'm liberal. Non techy. The week of the blackout i googled 'Reddit alternatives', clicked a few buttons, made a name and password, and that was it. I don't get why so many fedders think it's too difficult for others. It's a hell of a lot easier than Pinterest. I still don't get that shit.
If you consider reality to be an echo chamber, I guess. But I think a better definition of an echo chamber would be all of the conservative based subs that churn out the same provenly false bullshit over and over.
