Sure, there are always outliers and you can correct me if I’m wrong, but that’s just the overall impression I have.
(I wasn’t sure if !asklemmy@lemmy.world or this community would fit better for this kind of question, but I assume it fits here.)
Weakness, definitely. The range of “permitted” ideas is way too narrow.
I tend to agree with most common political stances on Lemmy, but still I feel I’m self-censoring occasionally.
Many instances intentionally want an echo chamber. Posts and comments are often deleted even if they’re not abusive, if they are ideologically opposed.
The problem doesn’t seem to be that instances want to cater to a unique political group (that’s why we have federation) It’s that most instances cater to the same or similar groups. I think in general it’s better that instances are differentiated by political beliefs. For example, i don’t like Hexbear. I just block it. But if hexbear and solarpunk were a single instance, i wouldn’t be able to separate the good and the bad.
But i agree that separating yourself too much from other ideas is bad, and echo chambers are bad in general.
