Controversial opinions on metal

You haven't actually presented any logic or supported your argument in any way, so we can't possibly have disregarded any logic yet.
 
BOO FUCKING HOO. I know, I should be ashamed of disagreeing with THE MOD. But I still don't like drone and Pokemon is still for children and gamers, who are often giant children.
 
But... unlike Slipknot, both have EXTENSIVE metal elements to complement their groove... every track both Pantera and Lamb of God have put out has been primarily metal, so flawed argument.

  • Lamb of God is metalcore/thrash/groove. Both metalcore and thrash are subgenres of metal.
  • Pantera is thrash/groove. Thrash is a metal subgenre.
  • Slipknot is fucking rock with groove. With the OCCASIONAL metal element. Does that make them metal? FUCK no.

So what form of music is "groove" derivative of?
