"My contention is that maybe only 5% of metal promotes the various things that you speak of, while 95% of hip hop does."
I think that this is false and totally biased. Roth can sing about being a gigolo and it will be considered fun and innocent while a rapper who raps about being a "playa" or a pimp is considered a detriment to society. Below is a link to a research paper on the topic that shows the bias against rap as opposed metal despite indications that both music forms are equally detrimental.

With all due respect, I don't consider David Lee Roth to be metal, although I suppose that is debatable. More importanly, however, you know absolutley nothing of the subject of which you speak. You know nothing about heavy metal, or the lyrics, whereas those of us here debating you are very, very familiar with it. Linking to wacko sites like you did earlier in fact weakens your contention that you know anything about the subject.
Good lord. What a loser study you linked me to. Some idiot from Winona State University? I read it, and I fail to see any support for what you have stated. You seem to very easily beleive anything that somebody writes that supports your position.
Oh, and by the way, Winona has a big brown beaver. If you were familiar with the subject area, you would know what I am talking about.
