Thanks for your reply.
It makes sense and is very relevant to me as my wife) was accosted on a train (near Melbouirne) a few years ago by three Muslim Lebanese teenagers with the same angst, obscene language and venom directed against Non-Muslim women (the language used is far too obscene to be uttered on this site).
Fortunately my wife was not a teenager and she could handle the situation, but it left her traumatised.
