Thew only reason to wear a mask is so that someone can’t identify you while you commit a crime. Very few exceptions, and burkas don’t look like they would do too well on a ski slope.
In most (if not all) parts of the US, one cannot don KKK robes in public.
The burqa/niqab is nothing more than a symbol of defiance against Western Culture.
If one wants to wear them, then, by all means, MOVE TO A MUSLIM COUNTRY like Saudi Arabia.
