An, indomitable, elderly lady I know has suffered a stroke and walks slowly with a stick. She got herself down to London for time with her daughter and to take in an exhibition and a show.
On the tube, she was sitting opposite 2 people in burkhas, she says it was obvious from their footwear, size, mannerisms and voices that they were males. She was frightened - I think rightly - and didn't know who to report them to. There are plenty of reasons for banning the burkha, the one you cite is just another - but we have weak leaders.
