I don’t understand these “That’s just how the world is. Shame on you for discussing it” comments. I think it is very much worth discussing this, even if the conclusion of the discussion is that it’s not worth changing after all.
You point out similar dynamics on Reddit, but it’s obviously not exactly the same. The design of Reddit is such that there is a much stronger tendency for main communities to arise. By contrast, lots of smaller communities on Lemmy look like ghost towns, where they would be much healthier if they combined numbers. “You’re free to do whatever” doesn’t address the systemic issue.
That said, I don’t think this is obvious either way. There are tons of benefits to the current system too. That’s why it’s worth coming back to this topic every once in a while. If these sorts of nitty gritty design discussions bore you, why are you on this community?
If you don’t want apartheid and ethnic cleansing of Palestinians, then you want to rape festival-goers. Those are the only two choices!
