More seriously...
It is interesting how most of the real advocates are "converts" rather than life long Muslims.
Also of note i show many moderates claim that there is nothing in the religious texts that means the enclosed dress has to be worn.
Apart from that I have no problem per se, but do have reservations in some circumstances where the lack of facial recognition can be a problem. Banks, shops and airlines for instance, perhaps less reasonable is the "cultural need" to have facial signs as communication. Hospitals, job interviews and a whole raft of other situations where much of the communication is through expression rather than what is said.
