Racism.

Racism is defined as a belief or doctrine that inherent differences among the various human races determine cultural or individual achievement, usually involving the idea that one's own race is superior and has the right to rule others.
It is also defined as hatred or intolerance of another race or other races.
I cannot comprehend that. I can't understand how someone can hate another person or another religion so much without understanding it or knowing the person. How can you look at someone in a hijab and automatically hate her? How can you look at the color of someone's skin and already hate him? You don't even KNOW them. You don't know who they are, you don't understand their beliefs, all you know is the outside appearances.
I don't understand how we can claim to be the 'land of the free' when we still have soldiers who can't marry the person they love because they are gay, we have people calling our president the n-word, we have people threatening to run over other people with cars because they wear the hijab and we have people afraid to practice their religious and personal beliefs. That isn't a free country.
