What Issue Does Your Fandom NEVER Address?

What's the "elephant in the room" in your fandom, some plotline, character trait, or fan behavior that no one wants to acknowledge? Is it that a character is worse than everyone says they are?

And do you think it's for the best that it's ignored, or should people finally talk about it?
