As humans, one thing we do is place people in categories. It's not something we can choose not to do; it's part of our cognitive makeup. Indeed, if we don't categorize, we don't perceive. But the old categories aren't any good any more. Can't use color (not because it's non-PC to use color), but because any color distinctions aren't reliable. Can't use any other ethnicity, either, for the same reason. Can't use things like body art. One of the sweetest, loveliest, kindest people on this earth has a shoulder arm liberally tattooed. Dress? It is to laugh. Again, I know a person whose dress screams "TART," but who is anything but.
So, how do we classify people? I offer the following methods:
1. How does this person treat his/her partner? Affection? Love? Tenderness? Sarcasm? Cruelty? Indifference?
2. How does this person treat his/her children? Children require infinite patience.
3. How does this person treat casual contacts? (Waitresses, bus drivers, sales clerks)
4. How does this person treat strangers?
