People, please GET OVER THE KORN AND FREAKING NU-METAL THING!
I am so freaking sick of hearing everyone (or at least so many people) whine and bitch about this stupid band isn't metal, and this band doesn't deserve to be called metal, and nu-metal freaking sucks.
More traditional metal is not likely ever going to be popular in the mainstream market ever, so just listen to the bands you like and give this entirely worn-out subject a rest.
If they want to call themselves metal, and they think they are, then who the hell cares? Categorization is such a compartmentalized way of looking at the world. And if people who listen to them want to call them metal, who cares? Are you offended because you're afraid your elitist metal is going to be tainted by an association with more popular bands? Well, it's not. It can survive just well on its own.
TOLERANCE is a nice philosophy when it comes to culture, race, religion AND music. If it's not hurting anyone, and despite many of the arguments I've heard I am sure it's not, then just let it be.
Sorry if I 'm ranting or sounding grumpy, but I just woke up, and I'm always grouchy when I first wake up.
