some clones can't handle it when people are different. they get scared and dont understand so they are slack bitches to reaffirm their feelings about themselves
and heaven help you if bust out of your little pigeonhole that they're so comfortable with. heaven forbid you should develop the self respect to talk back. suddenly you're a slut.
Same reason guys are nice to bitchy girls, low self esteem, the guy's good looking, etc. Why do bitchy girls date asshole pricks?
