While Fred Durst's band have repeatedly praised the 'Killing in the Name' band for paving the way in the music industry, bassist Tim Commerford is horrified that the two groups have any association at all.
He told Rolling Stone: "I do apologise for Limp Bizkit. I really do. I feel really bad that we inspired such bulls**t."
Mistakenly believing Limp Bizkit have split, he added: ""They're gone, though. That's the beautiful thing. There's only one left, and that's Rage, and as far as I'm concerned, we're the only one that matters."
The snub will not please Durst, who has repeatedly spoken of his love for RATM and insisted they inspired his own band.
Limp Bizkit regularly plays 'Killing In The Name' during their concerts and at a 2014 gig in New York, he even dedicated a song to Rage, "the rap-rock band that started this s**t."
Commerford has previously shown his disdain for Limp Bizkit, crashing the stage and climbing the backdrop during the MTV VMAs in 2000, when his band were beaten by their rivals in the Best Rock Video category.
He said: "It's aged like wine. I get more people that come up to me now. Back in 2000, it was like, 'Dude, I saw you do that. What was that all about?' Now, it's like, 'Dude, I saw you do that. That was so f**kin' awesome! I love that.' It feels more comfortable now to talk about.
"I wish I would've swung on that thing and brought it to the ground and just destroyed it. If I could do it all over again, I would've ripped that thing to the ground and shredded it."
