It's easy to anonymously attack someone who turns the other cheek. Sadly, when you don't defend yourself, ignorant minds see whatever is being said as an unchallenged truth.
As a creative mind, I always thought it a tremendous virtue that Snyder doesn't address attacks on him. Rather, if someone sought an explanation for a creative choice in his movies, he was always there on Vero or Twitter to answer someone that brought a valid question in a respectful manner.
I've actually thought about signing up for Vero to ask him what his favorite scene is that he has recorded in his films, in hopes that he would respond.
