With that framework, however you respond to the images is entirely within the realm of fiction.
I don't know about anyone else but whether it be fangirling over an actor or a character, I'm well aware that my response is entirely within the realm of fiction.
LOL I think at least 90 % of ladies' fangirling is completely harmless fun, and helps get the actor noticed, and that remaining percentage that goes overboard...
well... that's why there are policemen and restraining orders!
