Although face disfigurement may be a demoralizing difficulty the concept that everybody will acquire masks to remedy the problems of a minority of people seems somewhat beyond fantasy. There are laws now limiting the use of face masks in public and in general masking is not looked well upon for public use. In the age of terrorism there would be legal difficulties.

Some muslim countries keep their women covered with a thing that has a kind of screen in front to see and breathe through. Just extend that to the men, and you're there.

Mel Gibson made a movie, 'Man Without a Face' that had a theme related to this.

Personally, I believe we're programmed by evolution to shun others that are 'different' in order to exclude mutations which in many cases are detrimental. A facial disfigurement is not a mutation, but to say an ape, his 'instincts' have no way of knowing what might be a genetic disease verses an occurrance.

I own animals and I've seen how they tend to exclude and even pick-on the one thats a different color, even though sometimes a mutation or difference can be benificial.

What terrorism? You are afraid? Then it's your ism. Mask (or burka) away, nothing will change.
