Accepting differences

Many times in Facebook, twitter or any other social network website, I come across people who insult others because they are different than them either by a different race, color, look, religion, nationality country or [many other criteria. Correct grammatically but criteria is not the word I would use in this context. I'd simply say: 'etc' 'or anything else,' 'or whatever else']
And I ask myself, why we are like this? are we really having (I'd say: don't we really just have one identity , called "Human Beings" or and one country [called, you don't necessarily need to say "called"]  "Earth"?

Great entry and this is so true.. If only people could understand this!!! :(
