I wanted to share a pretty interesting social experiment done by ABC, which shows a staged situation in which a black woman is being discriminated by store clerks, and the reactions of the customers.
It seems that so many people claim to not be racist but when they're put to the test in public scenarios in which others are being discriminated by the majority or authority, they become passive and would rather have nothing to do with it, or even side with the discriminators when under pressure.
Check it out and think about the next time you're faced with a situation like this and how you'd react, really..
