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 ~~Arch~~ Linux btw are different - perhaps less sane?:-P
