i think racism is the worst face in our human society

I personally think racism is totally immoral, and obviously wrong. I don't understand, why would people judge others that are the exact same kind as your own self in such an offensive way? We judge the ones who talk behind our backs, but then we talk about the ones that we don't even know more than the ones that are speaking against us. What kind of good does it do to us while we are being racist and calling people names? I think, if everyone in the world can just hold back their thoughts toward others, just think through what you are about to say in your mind first, then choose rather to say it or not, the world should be able to be a better place to live. Everyone is talking about peace not war, love one another, then this is such an easy tiny step to accomplish a big thing. This is for the greater good! Don't you see? If everyone can just drop all their bad thoughts about a person, how many conflicts or arguments could have be prevented? A lot. There was never a choice for us to choose who we want to be as in our look, our race. All human beings should learn how to except someone as who they are, no matter what they do, or how they look. They are the same kind as your own self. So stop racism, it does no good no matter how you look at it. Do this not just for yourself, but also for the greater good, for the your community, and for the world that you are living in.
