The solution is to behave with civility online and you don’t get banned. No one needs to break instance rules.
If someone is incapable of doing that, why should they get to participate?
The fact that they happen to predominantly come with right wing view points is, frankly, secondary. It’s literally the bare minimum amount of effort in life to simply not be a nuisance.
The two main “hard left” instances have been defederated from LW too (hex and grad)
LML is ostensibly a general instance with a strong left wing slant. So I’m assuming those are the users you’re referring to. Every time I’ve personally seen a LML user step over the line for a given community’s rules, they have been banned for it.
Predominantly though, those users are capable of understanding rules and following them.
That’s literally all anyone needs to do.
It’s not really about political views. It’s simply about not being an asshole.
