I had thought HartFan's original post was sarcastic given the documentation that most wrestlers who aren't under their real name do not wish to be referred to by it, but apparently I was wrong.
Though I'll never understand kayfabe in the sense that while both actors and wrestlers perform under the premise of a character, referring to actors outside the presence of their medium by their character's name would be considered absurd, while referring to a wrestler outside their medium by their character is the norm while using real names is considered poor form
...On the other hand, I can understand some wrestlers changing their de facto name (Michael Hickenbottom indeed)
