Absolutely not, and I agree with you. But help me out - isn't the root cause of all the examples you list a lack of information? Case in point of many: don't people in general become less bigoted the more educated they become?

Call me a naive idealist, but I wonder if the information barriers erected by people to protect themselves, are, on a wider scale, actually what keeps bigotry and hatred alive?

Zuckerberg isn't a saint, so I'm not suggesting that there is any altruistic motive behind his moves. I'm just questioning if greater transparency is inherently a bad thing.
