Tons of people can't stand "marketing people", it's why so many people laugh at things like Bill Hicks' monologue on the topic [0] funny.

I like shiny new things as much as the next person. But I don't like marketing and I don't like being sold to. If someone's sole job is to convince me I need something and my life is worse off without whatever they're selling, why would I like them?
