The author of this rant is a pompous egotistical azz. However, I agree with his closing sentence, "There is no shame nor contradiction in recognizing both the right of women to wear a niqab and the fact that this is not something to celebrate".  Being atheist, I heap scorn on religious rituals of all sorts, but will vigorously defend freedom of religion; you have a right to be gullible.

Incidentally, I've seen quite a lot of commentary defending the right to wear a niqab; I've read none "celebrating" the niqab.
