omg. you have got so many things wrong i dont even know were to start...
-its Korn not corn
-Linkin Park have never been nu metal
-i like a lot of nu metal bands, and i know plenty about metal thank you
-nu metal is real metal. its a sub-genre just like death, black or speed
-In Flames arent violent
-there are very few people who like just nu metal
im sorry but what you said is complete and utter bullshit. as you can see from my sig i love Korn. do you want to know my other favorite bands? Slayer, In Flames, Metallica and Sepultura.
also, many nu metal bands are extremely heavy. Slipknot, American Head Charge, Mushroomhead, (early) Deftones and Korn are all just as heavy as many other genres.
Linkin Park are pure shitty pop-rock, but Korn not metal? even if you dont like them, you cant deny the fact that they are metal. what the hell would you call them?
dude...im not even gonna bother carrying on. plenty of other people will agree with me on this one. and from what you've said so far, it sounds like your the one who knows nothing about metal.
