Still & all, Dave ~~ I do, honest, get your point: but it is always the prominent noisy minority by which anything is judged. I won't do that Yeats quote yet again.

&, yes, we all have, probably, a Muslim friend or two who probably seems pretty secularised, and not essentially much different from us. But try putting these disagreeable goings-on before him for an opinion, & see if you get an outright condemnation, or (as I suspect would be more likely) a sort of embarrassed, rather squirming, response that adds up in effect to "I'd really rather not comment".
