Most agree that we shouldn't actively do it, but we definitely do it consciously and subconsciously. It's a very human trait, even if we don't like it. The brain just doesn't have the capacity to evaluate everyone from scratch every time, so it takes shortcuts, and 'accepts' people based on the way they present themselves. The kinds of clothes they wear, shoes they're wearing, and accreditation from mutually trusted institutions. I agree the shortcuts that cause harm should be curbed to the best of our abilities but we can at best notice it and correct after the fact - but it'll still happen.
