Marilyn Manson is amusing.

I like how they caught Billie Joe looking like a retard in his picture.

He looks like a retard all the time

I'm almost positive he carries that goth fad around all the time. Not just when he's on stage.

Goth fad? Since when was he goth? Since when was, what, more than ten years just a fad? Do you seriously believe he dresses himself in the leather thong and all (or other such strange costumes) on all occasions? Even his everyday attire is a little odd, yes, but that doesn't really mean much. He isn't a bad guy for it.
And the weird stuff he pulls off on stage is for the show. He's a good showman.
