Screamo is basically emo but they scream, Slipknot is metal they are not, nor will they ever be screamo or emo.
I don't listen to any Screamo or Emo music, I listen to Rock, Alternative Rock, Hard Rock, Metal, Death Metal, Black Metal, Hip-Hop and Rap. I will never listen to that gay Emo or Screamo shit. I maybe a Music Enthusiast but that doesn't mean I listen to Emo or Scream nor do I tell people to listen to that shit. I hate emo and scene children, they piss me off, Emo kids = Little rich white kids whose mommy and daddy decided to take away their $500 allowance or their brand new corvette. I'm a poor guy from the ghetto, no way in fucking hell I would listen to Emo.
