Nancy - I found your comment on the "dehumanising" aspect fascinating.
I think many, not all, but many of the women choosing to adopt facial and bodily covering are a younger generation, politicised within a certain contemporary political discourse. As another poster has pointed out, there is a definite generational and rebellious element to the decision.
It's a visible statement, clearly so in a liberal country such as Britain.
Part of the "message" it conveys is precisely that of a question-mark raised against dominant, capitalist, predominantly Western ideas of what constitutes "humanised" and particularly "humanised female".
I do think that the decision to take the veil, and so on, can be subject to a critique, even criticism. But only if you have initially taken on board the position that the decision stands for. And thus some of the critique of those mainstream Western values that are implied by the decision.
Much of that critique is very, very similar to the decisions of Western feminists who were/are outraged by the emphasis on a commercially, even patriarchally defined notion of what a woman must do/look like in order to count as a female human.
We have many threads on here about how much pressure our children come under to meet that standard and how very unpleasant it is for us as parents to resist that. And, I suppose we have many strategies for resisting/living with that pressure.
So I do think that, although you, and others, may indeed return to your position that the veil is dehumanising, you, and others need to circuit through your own criticisms of contemporary, mainstream culture, in order to richly inform that position.
