BS actually means Breeze Shooting, a general heading for non-music discussion & a more levititious exchange...

Meanwhile...

how on earth did you come up with that?!

It made perfect sense in the context of your other arguments, for example: it's much more difficult for tourists to terrorise. It actually reads like you disagree with the Left for allowing in immigrants because their sole intention is to become terrorists. If that's not what you meant, I apologise, but strongly suggest you implement a regime of disambiguation.

and I hope we can stay on such matters, as RM requested

As I suggested above, this thread was never simply about Morris Dancing, beginning as it does with a culturally divisive catalogue of English Dances & Musical Instruments, most of which amount to the hobbyist concern (as oppose to the living tradition) of but a tiny minority of the 50 million or so human souls currently resident upon English soil, whatever their ethnicity. You might as well ask for a massed model railway display or a parade of vintage Ford Anglias.
