browsing through All has so much pro-fascist posts coming from lemmygrad that it drowns out all the other instances. I'm surprised they're even federated by default but we should have an option to block instances from All if lemmy is deadset on federating with them just because they are fascists with a red and yellow flag...
(before the Tankies start posting about how they aren't pro-fascism "Fascism is a far-right, authoritarian, ultranationalist political ideology and movement, characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a natural social hierarchy, subordination of individual interests for the good of the nation and race, and strong regimentation of society and the economy" which all describe the Z movement in Russia they gleefully support in multiple posts)
There should be no default instance. That just leads to people all collecting on a single instance.
There already is no default instance. lemmy.ml isn't an instance that aims to be for everyone.
If you don't like them federating with that particular instance you may want to look at other instances that better fit you.
The only thing that I think could be changed is the name of lemmy.ml. Its name and the fact that it is the biggest instance may lead to the false conclusion that it is in some way supposed to be the default instance. Maybe join-lemmy.org should be modified a bit to suggest a lot more random instances.
Maybe for the "All" there could be a sort type made available that favours posts coming from less active instances. That could make the smaller instances more popular (favouring decentralization), and reduce the by some excessive perceived noise that may come from some instances in the all tab.
