What's IT called?

The fear of clowns is called coulrophobia. Apparently people find clowns scary because they wear masks and don't show any real emotion (smiles painted on and whatnot).

 

 

Superheroes wear masks and don't tend to show emotion (take Batman's monotone voice as testament) but people don't seem to be afraid of them.

 

Of course not! I hear you say. Superheroes help people. Aren't clowns supposed to entertain people, make them laugh? How is it one good intention can be accepted while another cannot?

Another Google search reveals maskophobia is the fear of masks while metamfiezomaiophobia is the name given to the broader fear of mimes, clowns and people in disguise. I supposed that would include superheroes?
