If a dude's that much of a perv, a little thing like niqab won't stop him from getting "turned on" (he'll probably just use his imagination, lol). ;-)
I've seen men getting turned on by hands! Freaks...!!
So yeah, the reason I support naqab is not because it will protect us from pervy men (coz it just won't in the present times), but because its a woman's choice and I really don't see how one can use the words "women's rights" and "ban naqab" in the same sentence..
Anyhow... sighhh...
