To quickly make it clear: this thread is specifically about fandoms you are a part of and what part(s) of it you have some real issues with.
I'll start off with a pretty obvious one: I'm a fan of Super Smash Bros. but I really dislike a good chunk of the competitive Smash community. Be it hardcore Melee fanboys who shit on anyone who happens to prefer other entries in the Smash series, or toxic competitive players who shit on other players for maining a certain character. EVO 2018 kinda helped to only prove my point in varies ways be it certain Melee fanboys who literally boo'd at the announcement of the Smash Ultimate Direct during the Melee tournament (I'm basically turning into Pat from Super Best Friends when it comes to how I feel about the hardcore Melee crowd), or what happened during the Smash 4 finals when the two finalists were boo'd over their choice of character being Bayonetta (I almost don't blame them for wanting to troll the crowd, granted they could have handled it a bit better in the end).
