I'm unsure on this. I think that, ultimately, people should be free to wear whatever they choose. But that does not advance this argument any further, given that as far as I'm aware, a overwhelming majority of female Muslims detest having their femininity repressed. But in the interest of balance, I do know somebody, first hand, that does quite enjoy it.
I could go down the route of telling you about a time when I was walking around my local town dressed as a ninja, got asked to reveal my face as I was entering a shopping centre (naturally, I obliged courteously). I'm not sure whether I need to finish the story, but there was a veiled lady walking through totally unimpeded. That did frustrate me somewhat.
If I were to argue in favour of the ban, I would go about it by saying that I believe it would not be a ban on women wearing the veil as such, it would be a ban on the male dominating the female, dictating what she is to wear and repressing her femininity. A ban on that is something I would gladly argue for.
