Instead of "valid", think of their security concerns as understandable in times of unpredictable terrorism.
The word "valid" would convey more approval than I'd grant them.
I do think that Muslims will have to adjust to women showing their faces to authorities as needed. This could very well mean male authorities.
I've already said that facial recognition is useful for security. Is more needed?
Okay, i don't want to bug you so i'll state upfront that this much i can agree with to an extent, but let me clarify something (just for the sake of clarity because i think we misunderstood each other at some points). Cars, for instance, cause plenty of deaths. Not security concerns, actual deaths. So does smoking. Knives for instance, are used for murder. Do we ban any of those things? No, because for the most part (except for smoking) they're used properly. One needs strong or compelling reasons to do something like that.
The niqab or burqa, is a dress worn by women belonging to a minority in France due to religious reasons. A minority which was already complaining about discrimination in France, which is also like i said a country that advocates personal freedoms. Now, they supposedly have a concern (i don't accept that, but for the sake of this clarification) concerning it being used as a cover for criminal acts. Okay, is that enough to ban it? No, and you do agree to this much as i understand. Thus,
this decision, of the ban, without it actually being a demonstrated security concern (by which i mean a concern justified by numerous incidents for example), is neither understandable or agreeable. Also because they could have handled it differently, using the way which we all are in agreement on, revealing the face in the needed or required places and times.
That way, would have been the normal procedure, the easiest to enforce, the one causing the least number of complaints and would not oppose France's values. Assuming the security concern is actually true and is a basis for this, i understand why you would sympathize and/or understand
it (the supposed security concern), i don't object to that part, what i do object to however, is understanding and/or sympathizing with the
decision of the ban. Your reply this time leads me to believe that you don't, but that you just sympathize and understand the supposed existence of such concern, to which i can agree to an extent (and the only reason its an extent and not fully of course is because i don't think it actually does exist or at least that it is supposedly part of the basis for this ban).
