Tim Commerford: Colin Kaepernick is 'Rage' Worthy

Colin Kaepernick is getting some big time support over his national anthem controversy ... because Tim Commerford thinks the QB is a straight "badass."

The bassist for "Rage Against the Machine" was leaving the London in NYC Sunday when he applauded Kaepernick for standing up for his beliefs, knowing there may be repercussions.

He even says the San Fran QB has an open invitation to join his new group, "Prophets of Rage."

Commerford is no stranger to public protests -- he famously climbed a wall during the 2000 VMA's to protest Limp Bizkit beating them out for Best Rock Video.

BTW ... he's still not over the loss.
