This is extremely extremely unlikely of course, but hypothetically speaking if I ever got a cease and desist from a real person I wrote about - I will. Immediately. And I won't whine or bitch about it because, well, they have a legit right to protect themselves. Further, what I would ABSOLUTELY NEVER EVER do is try to deflect the spotlight off myself and onto the rest of fandom.
Sure I'm emotionally involved with all my writing (amateur and average as it may be). But my life will not end and my heart will not break just because I can't put something up in the public domain. And I sure as hell won't use it as an opportunity to be the newest wank!queen on the block.
And you know what's really rich? - Claiming that they're helping further a person's career. SERIOUSLY? How, pray tell, do you further anyone's career by insulting them and degrading their public image? The definition of "Humor" is a subjective one, different for different people. So if JA himself does not find their "humor" humorous, well that's reason enough for me. I'd advise these people to mind their own careers for a change, might even end up doing something productive.
