Well, if you look at poor widdle fragile Blair Sandburg (who takes out terrorists with a snack machine in his first day on the job :), Daniel Jackson (who insults magalomaniac aliens for fun), Spencer Reid (who managed to outthink a psychopath while tortured and drugged)... the list goes on. I've even seen it with Avon (Blakes 7) who would slaughter anyone who tried to 'poor baby' him, without turning a hair. And Rodney Mckay, who is canonically armoured with a steel plate of sheer ego.

In some way I can see the appeal, it is tied to the appeal of h/c and comfort fics, but I firmly believe that you can trash them without turning them into frail and fragile (and wet and weedy weedy) flowerlets...
