Sure i see that also. When Zoro gets something negative somewhere, the same people come up and spread toxicity from the other side and i am tired of that too. Honestly, i get headache thinking about the next weeks when (just in my opinion) zoro will fall against Kaido (which wouldnt be something to blame anyway, cause he is doing impressive right now!), the trolling against the zoro fandom comes up again.
But this is a circle. Zoro gets hype, zoro fandom gets toxic AF, Zoro gets dehyped, zoro haters get toxic AF. The main situation right now is just, the zoro fandom in our forum is way bigger then real haters (and i mean trolling haters, not people who just arent big zoro fans), thats why the toxicity right now is, in my opinion, even bigger. Just look at the numbers on strange zoro thread the last days. Also i lost counting how much insults and provocations me alone deleted here and i am absolutely not the most active moditing person in this thread.
So yes, i absolutely see the other side being toxic AF too when the parallel situation occurs, and i am tired of that too. But one toxicity doesnt make the other one better or more acceptable.
Edit: Also, in my opinion, overhyping will always lead into a massive backslash. So claiming now for example Zoro would Mid Diff Kaido right now (someone claimed it the last days), will automaticaly lead into a massive backslash when it gets debunked.
