NIN certainly gets into the rage as well, but industrial music has a lot in common with metal. I think most would consider it a sub-genre of metal. Metal, however, is extremely varied these days. The music is often aggressive, but there are metal ballads galore to choose from, and the message can range from uplifting to just plain silly, though you are accurate in as far as "rage and intensity" being where most metal songs fit.

@Thomas II - That is an awesome video. When you are as great of a guitarist as Zakk Wylde, you can make any guitar sound good.
A lot of the music I choose to listen to these days depends on the mood I'm in, which is rarely rage.
Not only that but metal is often the polar opposite of what I'm likely to listen to. Usually I'm in to more chill, relaxed, cool, calm, soulful music. Might partly be a product of my personality, another part of it might be introversion. I rarely crave music that's too upbeat, regardless of genre, which I've come to understand is often correlated with the extraversion spectrum. I'd assume metal fans lean heavily extrovert.
I don't think rage is a necessary mood for metal, and it may even be detrimental if it causes you to do violence or something stupid. However, metal is good for an outpouring of emotion, which could be rage, or excitement, or a number of different emotions. Now, I was raised on classical, but always had a soft spot for the louder, more powerful pieces, and in that regard, find it analogous to metal. Holst's Mars: The Bringer of War, Wagner's Die Walküre, and pieces like them were the metal of their days.
I'd also think you'd be surprised to find that there are more introverted metal fans than you might think. Metal is often seen as rebellious music and it can lift up the feelings of the down-trodden, the bullied, and the isolated. It may well help the introverts to come out of their shells from time to time.
