I'm sure it is, which is why I make an exception for kink--kink fic can and *should* do these things. But dropping it into a fic that is what becomes a problem to me, because like parody fic, it has its own rules on how to proceed. A fic not under these tends to fall under the "I Feel This Character Is Upppity And Needs To Be Taken Down a Bit" or "He Is So OMG Pretty So Of Course He'd Choose This As a Totally Normal Thing To Do!" *shrug*
