That's great!
Well, criticism is one thing. If someone didn't like TLJ and writes Rian Johnson on Twitter "Didn't like the movie, Luke was my favorite character and now he's dead" that's hardly toxic. If they say that
Rian Johnson is worse than Hitler or even send him death threads that's a whole nother story. And you should consider that harassment, as that is what it is. I also wonder in what way exactly Rian Johnson etc. acted online that you're reffering to here. The "worst" thing he did that I could find was calling a twitter user who posted something snarky under a post about Carrie Fisher's passing a "manbaby".
The mods are entitled to their opinion. Of course they have to be fair when it comes to active mod duties and letting a comment like "Go die you fucking conservative" fly while giving someone who said "Go die you fucking liberal" (both hypothetical posts) a pass would be
very wrong. But that isn't the case here, plus the particular mods who participate in this discussion aren't even mods of this sub-forum and thus don't have any actual power here. At least I think that's how it works.
