Seems like anything can be taken to extremes, sending death threats to the author because they wrote their story the way they wanted and not some fan's wet fantasies definitely seems overboard. I remember liking Zutara over Kataang in ATLA, didn't happen, who cares, time to move on. I dislike Oden, and can rant about his character, but I don't hate Oda or his editors, and am simply happy that we finally are over Oden in the story arc. As much as I like Sanji, I recognize that Zoro is consistently written as stronger of the two, so I stay away from "Sanji vs Zoro' discussions. For me any kind of toxic behavior is annoying, regardless if it's crazy shipping, character bashing, or powescaling ending up in a series of personal insults like "you're a retard if you believe character X is stronger than character Y". We have our different tastes and opinions, when it comes to characters and romance. As for versus threads - well, it's more like a fun "what if" exercise, sometimes it's fun to imagine a fight between Doffy & Crocodile, as long as the discussion doesn't get into "it's true just because I said so" and "you're stupid because you don't accept my opinion as a fact" territory.
