Because there's no need to beat a dead horse. They were wrong. They were corrected. It happens every day in almost every board. It's not helpful when people are wrong but, whatever, because there's plenty of people here who are right and practically follow these games as if it were their religion. If the clutter is particularly obnoxious, it gets weeded out. More or less saying people shouldn't be here if they're wrong or naive about a subject is, itself, obnoxious. The example I've been giving for years is how Mew2King thought Mewtwo was one of the best characters in Melee when he first joined. He was hilariously wrong but, whatever, he learned otherwise with time and everybody here can do that and should be allowed to do that. People can be wrong and they're allowed to eat crow if they are. Saying they're not part of the community based on how much they know goes against the point of these forums to begin with. People come here to learn and there's a myriad of resources available to them here including the best players in the world in each game. Being wrong isn't a capital crime and simply correcting people isn't as big of an inconvenience as you're implying it to be.

It wasn't. Mario was one of the characters who didn't receive any changes in this last patch. The difference you experienced could have been based on the stage you were playing on having a lower ceiling.
