I have no problem at all with hijab (or indeed any other head covering) - I can see who I'm talking with and it's fine. The burka is another matter, it has no place in any society let alone a secular, western one.
Like others, I do take issue with the concept that the hijab equates to 'modest dress' which, by extension, means that not wearing one renders a woman 'immodest' - that's a load of fetid dingo's kidneys and deserves a firm rebuttal.
