Good luck finding a completely unbiased person, much less about a million of them that would work for the crappy pay and lousy attitude from people.
The world isn't the candy coated dreamland that the cartoons told you it is. People are inherently xenophobic. If you never see a black or white person for most of your childhood, a black person will be weird.
I thought my black GI Joe was wearing a mask. Then my parents explained that there were lots of different colors of people. I thought it was weird.
No one asked for my opinion, but here it is:
None of you have ever been completely tolerant. You've slipped, probably on many more occasions that you'd like to admit. It's alright, everyone has... But please don't sit there and act like you're the freaking perfect person so that you can avoid being flamed by other people who don't want to be flamed by you for being honest.
