Edit.
Flipping the coin. Instead of asking about purple dragons to theists, what about agnostics.
Do you believe there could be a purple dragon if you had proof from a disney movie?
Not god. A big, fire breathing, Sword in the stone, purple dragon.
No one in this thread OP made the claim purple dragons exist (though they seem to on disney.) No hidden messages
Just as if I asked you in person without referring to any religion whatsoever. Do you believe a fire breathing purple dragon could exist if you have proof from a disney movie?
Do you believe there is none (yes or no) even though disney creates dragon movies provide otherwise?
Being an (ex) graphics artist who has contributed to several films, fantasy, educational and scientific (but not to disney/pixar), i can assure you, a Disney film is proof of only one thing... that Disney makes films.
