A phobia is an anxiety disorder and has nothing to do with genuine dangers.

The vast majority of the world's Muslims are just ordinary human beings who happen to follow a primitive religion that helps them cope with the dilemma of being conscious and mortal. But there is a significant percent of this group who genuinely believe in a deity who wants them to convert or kill infidels. It's not a phobia to take precautions around these folks... it's plain and simple stupidity to deny they are a threat.
