Why Do People Judge Others By The Way They Look Or By The Music They Listen To?

People in the world constantly judge others by the way they look, or by the music they listen to. I am judged constantly for listening to Insane Clown Posse an the rest of the Psychopathic Family just because other people dont like them an if they got to know me then they would be like wow i cant believed i actually judged him for that. Im really easy to get along with an i dont understand how people do the things they do to others. I think everyone should be able to listen to the music they want an not be judged by the more popular kids just because there different doesnt mean they should be treated different. I think the more popular kids should see our point of views an what goes on in our not so perfect life after school. I think they should just once go through what we do and i think then they'll understand why we listen to the music we do.
