I'm not hating or judging for that matter. I have no problems with the bands you like. Your actually entertaining me. Your honestly not even old enough to know about true underground hardcore. But I digress, you could have started at a very young age.
But to say ICP are still underground is the same as saying Metallica is still underground. Their roots are underground, and many of their followers, including you, have probably been fans since day one. Wait...werent they formed in the late 80's? Yeah, your def too young.
Anyway...quit trying to act so hard. You like the group, f**k anyone who has a problem with that. I dont have a problem with the with you or the band. Lets just be friends.
