I'm sure we all have been included in someone's collective - deliberate or unconscious - slur, stated as "you people", meaning a group from which the speaker wants to distance hirself. I think the first time i was annoyed by a "you people", the speaker was putting down immigrants, but i've been subsumed under many groups since.
What people are you lumped in with? What people do you really belong with? And ho do you feel about hearing that phrase?
