I’ve heard people talking about e.g. not subscribing to lemmy.world communities (because they are the largest instance), and others like Lemmygrad seems to be defederated by quite many instances. But what about lemmy.ml? Should that instance and those communities also be avoided? The “issue” is that many large communities seem to be based on that instance. Like [email protected] and [email protected]
Personally, I don’t think so. Like you point out if the Marxist Leninist instance has content you enjoy then why would you avoid it? - perhaps just don’t get into overtly political discussions / arguments.
You don’t have to be trans to visit or use a trans instance, non-anarchists can be on the anarchist instances, but do remember where you are and, most importantly, that you’re a guest/visitor and try to act accordingly. The same advice goes for .world
I’ve had no problems wherever I’ve gone - so far.
