I think it’s a self-selecting process. Muskbros who begin to doubt their Lord and Savior will stop following him and talking about how great he is, so every dumbass decision he makes shrinks his core fanbase, but also results in them being less bothered by all the terrible things he does. So it results in this weird situation where his hardcore fanbase have long since abandoned any semblance of reality, and if you reject reality, there’s no point remembering things someone said or did a decade ago.
