Bellydance veils and Niqabs?

Hey if you dance, then I've got a question for you. Many bellydancers really hate the idea of wearing a face veil because of the idea of it giving a nod to the oppression of women back in the olden days, but during all of the veil dances that I've seenon youtube, why do most all of them draw a veil to their faces during the preformance? Does it mean anything? Thanks. (I know it's a dumb question, I'm just curious.)
