As a WWE fan (I lapse and return, currently watch a lot of it), I think all of us over the age of 12 feel dumb about it on some level. We happily refer to ourselves as "marks," which is old carny slang for a sucker or a rube. But we watch it because it's mindless escapism aimed at our basest instincts, not in spite of that fact.
But yeah, there's a level of self-aware irony in that fandom that is clearly lacking in the theme park fandom (which I am also obviously a member of).
