Some societies believe it is acceptable to judge people based on their appearance. Arguably, most people do it instinctively. It is just that in America it was deemed illegal. I know there's an epidemic of plastic surgery taking place in some Asian cultures - people getting cosmetic surgery so that they can be employable.
Right or wrong, that is how some societies are functioning.
Sure, it is, and that's why you may not require one. But I can see why people would want that, even with no malicious intention, which was your question :)
