There’s a reason the current Lemmy sourcecode is named 0.19.8 - this is beta version software, awaiting very many changes to reach completion. Heck, reports don’t even reach moderators on remote instances yet, as the whole drama with 196 is showing (they left the mod reports there for days, then got mad when the instance admin did what she said she would and cleaned up in the absence of the mods being willing to do anything about the situation).
But people either don’t know Rust (it’s reputedly difficult), don’t want to deal with those developers, or simply don’t want to help with the writing of code. Hence the creation of K/Mbin, PieFed, and Sublinks to deal with the former pair of issues, though not catching up to feature parity with Lemmy yet (except PieFed is already quite ahead, in some ways even though not ready for the masses in some fewer but more foundational and crucial ways).
But - and this is crucial - someone isn’t going to be able to block things unless they first have an account. It’s like saying that a particular general location (like a city or a nation) has no crime… if only you avoid the “bad” parts (but where are those even, and how are you supposed to know especially before you get into them - also, are there even any parts that aren’t bad? it’s a valid question, to someone who does not yet know?)
So you are correct in the sense that Lemmy != “Alt-Left Nazi”. What I said though is that we are an Alt-Left Nazi “bar”. We are not totally that thing - some of us are simply here, hanging out, having a drink, doing our own thing(s). But there are Nazis here (or rather in our case, the Alt-Left instead of the Alt-Right).
And that political content is everywhere. Well, not literally, but like if you browse by All or enjoy any kind of “news” or especially “memes”, then it’s really super difficult to block out. Someone used to Reddit simply won’t bother learning how to navigate around the Alt-Left spaces. We who use
ArchLinux btw are different - perhaps less sane?:-P
