Fun fact : it's my first ever post on any lemmy instance/community 
...which is messed up..
Okay tbh I don't know if I should have posted this some place else or if here is just fine 
So I'm brand new here, I've joined as lemm.ee was going to shut down. I only chose Hexbear because of how big and active it is, and of course for all its shade of leftism (being far left myself) but tbh that part was just a plus for me, what I wanted more was an opened enough instance, an inclusive one with enough peace of mind (not having to deal with unhinged/oppressing posts/comments daily).
But I started noticing that actually Hexbear had been defederated from some big instances like lemmy.world, upon trying to understand why I stumbled upon lemmy.world ~~BS~~ post explaining they did it for preemptive reasons (wtf ๐), obviously I just dismissed lemmy.world entirely and continued enjoying my time here. But then I noticed other instances like Blahaj blocked Hexbear as well and a bunch of others, I never found out why.
Then, while trying to understand what's with all the defederating I stumbled upon a lot of negative noise against Hexbear, claiming you lot are doing some horrid stuff like war crimes denial, trolling, hate speech, spreading pro-Russian propaganda (like anti Ukrainian stuff don't misinterpret me here, I'm fine with anti-western views or western propaganda skepticism), so much so I don't really know if what I read was some kind of fascists trying to slander this place, or people confused about Hexbear political views, or if it's linked to some Hexbear history I'm not aware of... It's just weird because so far I haven't encountered anything I could hold against this instance, for all I've seen you're all sweet and making nice content, haven't seen anything unhinged, but what makes me uneasy is this defederating thing, I can't help but wonder why.
I'm really confused. Can someone explain to me what this is all about ? Is it just some right wing noise, some unknown drama or what ?
Edit (in case any of you see it): Thanks a lot everyone for all your answers, kind words, jokes, emojis and for being so welcoming. What you all said was very informative, and most of it I sadly expected. Having taken a liking to lemmy I knew that whatever I'd learn it'd be a cause for concern, it saddens me that several instances, big ones at that, would just make more room for the far right by suppressing leftists and spreading hate. As always in any such case I can't say I'm surprised but it worries and disgust me nonetheless. Anyway I'm glad I found this place :)
A lot of it is liberals (and to a lesser extent: anarchists), but hexbear users are pretty argumentative (not an insult necessarily!) and tend to flood threads giving the illusion of brigading (happened on reddit as well with r/cth).
edit: if you want to federate with everyone, piefed.social and lemmy.zip are pretty good.
I think another big part of that with hexbear is that 1) it was a relatively big instance before people arrived to lemmy so it looked like an army of people disagreeing with someone when they were wrong, giving the appearance of brigading, and 2) down votes don't exist in this instance so when someone disagrees with someone else they have to write a comment to them.
Hexbear is definitely argumentative, too, but it actually seems less so than it used to be to me. Or maybe all the defeding made it less. Or maybe being here so long has made me see other sides to hexbear. Idk.
Speaking of being big and loud, does Lemmy still have that bug that makes our emotes still render extra-large on other instances? Or was that just a thing in the early days?
they're small enough now luckily. They still look a bit too big to be emojis though.
That bug was fixed
shame. that bug was fun
It still kinda happens for me in Raccoon on Android, thankfully.
Who needs to read what you lot have to say anyway! ๐ (I'm kidding, I appreciate hexbear and .ml the most on Lemmy.)
