Misogyny and terrorism are two unconnected things, even if some misogynists are also terrorists and some terrorists espouse misogyny.

The answer has nothing to do with any of that. The attack on the islamic veil is an attack on islamic society by the West for no better reason than it is different. The veil shows that the wearer has high moral standards and virtues that were last seen in the west some time before the First World War, and the West can't deal with that. Instead it sees murderers and terrorists hiding behind the veil in order to bring down Western society, when only a handful of men are known to have adopted such a disguise.

The sensible way to find out who is under a veil is to get another woman to look.
