The burqa should be banned in places only where it would be a hazard to the wearer and people around; i.e., in a McDonalds, where the long garment could snag on a fat fryer and easily splash on other workers, or in a factory environment, where it could easily be caught in machinery. The workplace should be a religion-free environment anyway, so that's the only place I could think of where it would actually be necessary to ban them.
