Hate is used in many ways. Hate can be an emotion or an action. It can mean anything from a mild aversion to an all-consuming detestation. A person hoping a sports team loses is often called a hater, just as someone who violently abuses a person because of his or her beliefs.
Am I a hater? If the definition is truly that broad, then the answer for me and every other person must be yes, for we all have aversion to some things. Since everyone is a hater, the important question is no longer who is a hater, but what are the restrictions of the hatred. For instance, we should not hate the person or people that hold to beliefs we find aversive. Christian hatred is restricted to an aversion to the evil itself. Christ said plainly, "Love your enemies."
All too often, acts of hatred are committed in the name of retribution for perceived hatred. If hate is so wrong, why use hateful rhetoric or actions to counter it? Hateful acts are not a logical way to counter hate. Christ taught a better way.
Don't hate on haters.
