Actually, I think peoople are very very aware that giving the slight treatment, disparaging body language such as rolliing their eyes when you say something, etc etc is demeaning, and damaging - that is exactly why they exclude/shun/exile/belittle because they want to undermine you, make you lose your self confidence, make you full of doubt, make you beg for some crumbs of acceptance from them. It's all about domination and control, via humiliation.
