The Fallacy of Rights and Wrongs

I think one of the biggest fallacies as a human being is the belief of right and wrong. When humans think of a situation being "right", they think of any other situations as "wrong", thus limiting themselves to understanding or appreciating the true situation. The truth is there is no such thing as right or wrong. There is only the matter of what is. I am not going to argue that Hitler wasn't wrong. He did kill millions of Jews. However, I _choose_ to apply a moral standard, and condemn him for what he did. He was "wrong" in my eyes. However, many injustice in our world can be avoided by not assigning what's right or wrong. Religion is the worst offender, dictating themselves as right, and everyone else wrong. Homosexuality is wrong? You haven't even started to consider talking about human rights. Girls should not be allowed to work? They are half the economy for goodness sake.
