"Normal is a setting on a washing machine", to quote a recent Tom Hanks story.

The Amish and the Doukhobors have both done any number of things in the past that others have considered anti-social or insulting in their refusal to fully integrate into society.  It's not exactly the same, but it's of a kind.

You use the word "right" again, but you don't know what it means.  A person can identify themselves verbally.  There's no need to see their face, or do you think government services shouldn't be delivered over the phone or the internet? 

Obtaining government service is a not a social call.  It is about service delivery.   If a woman wearing a niqab gets on the bus, puts the right fare in the slot, and then goes to her seat, what exactly is the problem?  Why does the driver need to see her face?
