You know, sometimes you need to take a deep breath and split the users in your mind. There are people discussing rationaly, still with a grain of bias for a character (Blother, rerere, for example), and then there are just fandoms who ignore everything not perfectly fitting their headcanon about a character. With the first one, you can discuss and even when you are at a different point of view or have a different opinion, its fun and you can enjoy it. But the second kind of user... For me its just trolling and in 95% of cases i just ignore them.
