There are several points to address. First of all, although there are many well-known, respected scholars who have declared that a woman may leave her face and hands exposed in public, I have yet to hear of even one who has said that it is disliked for a woman to cover even more of herself by wearing a face-veil and/or gloves. In fact, what such scholars have said is that at a minimum a woman must cover all but her hands and face, and that her reward from Allah SWT will be even greater for taking extra steps to conceal herself further. (And Allah knows best.) This is the so-called "least-conservative" viewpoint, so it is difficult to see how ordinary Muslims have come to criticize pious Muslim women who are simply seeking the pleasure of Allah SWT by veiling themselves fully.
Think about it carefully: would we ever think of criticizing a Muslim who fasts extra days outside of Ramadan? Do we belittle the Muslims whose prayers exceed the prescribed daily five? Are we upset when Muslims give more zakat than required by Islamic Law? Of course not. We admire such people for their apparent dedication to Allah SWT, just as we should admire Muslim women who cover their faces for the same reason. Whether they veil because they take the so-called "most-conservative" viewpoint that covering the face is a requirement of Islamic Law, or because they simply believe that they will earn extra reward from our Lord and Creator for doing something more than they have been asked to do is of little importance. Praise be to Allah, veiled women are engaged in halal, and that is the bottom line.
