I pretty much agree with all of this, and even though alot of people do refer to new heavy music they don't like as nu-metal (hence St Anger getting the tag), I don't think it is a negative thing, and there is some nu-metal that is actually quite good. For example, Disturbed's 'The Sickness' is definately a nu-metal album, because of the style, but I still think it is a great album. For me, it is more of a label of style that fits the genre (as said by everyone earlier, Korn, Deftones, etc), but yes, people do use it as the label of new stuff they don't like, and they shouldn't.
