Now, this isn't a slight or dig or insult towards you at all....let's preface this with that so it's clear. Not trolling, not insulting, k?
Do you not think that there's even the most remote of possibilities that he literally just does shit....pantyhose, whatever...paints his ass pink, wears a dead ferret on his head, whatever....and knows that a ton of his fans (as I stated) will automatically assume that there's some super deep meaning behind it all? In my opinion he is. He knows that at this point in whatever is left of his career he can get away with that still. Hell, he isn't the only one. I'm sure Bowie, NIN, whoever...they can do something completely random and there is BOUND to be a pantload of people on Facebook simply just overthinking it. 'He did this because ____ and _____ and you just don't understand, man...'
I find it incredibly difficult to believe that Marilyn Manson, as you put it, wore pantyhose on his head as something in 'the context of his personal mythology and history of self-expression' but that's E X A C T L Y what he knows a large portion of his fanbase will think! And they buy right in to it! That's why I'm baffled. What artist hasn't done some 'self-expression'?? They're musicians...that's sorta the point.
