Why do goth, punks and emos don't like preppy people?

I am just wondering cause my friend Kelly is goth and my friend Wes punk. When I met their friends (goth and punk mixed) they hated my preppy friend Jen and told me aside why is a cool kick ass punk girl like me hanging out with a annoying prep like her? I am just wondering is it just my friend or do they hate everyone?
