I wonder if anyone has any views on this question? There seems plenty of debate about circ on the Internet at the moment and I note that several clinics offer the procedure on demand in the London area inexpensively. Somebody must be making use of these services! At the same time there is a very strident anti-circ movement in North America. Circ has always been a sign of (upper)class origins and social privilege in Britain, hence the expression "the knobs".
