From the words racist and sexist, comes a new -ist word. A genrist is someone who things some or one music genre is superior to another, just as a racist would think their race is better than another. Most genrists consist of people who love rap, but hate anything that includes a guitar, while some genrists believe that anything that rap shouldn't be considered music and is a disgrace.
