Atheists, is not the burka a good thing to wear so that you would get to know the woman without the looks?

Personally, I don't think so. You'd get to know the person without looks, yes. However, it would be much harder to get to know the person. Maybe I'm misunderstanding burkas, but it's so much harder to communicate without seeing a person's face. You'd lose a large "something" in communication with that kind of barrier.
