Grohl is an advocate for LGBT rights. He has worn a White Knot ribbon to various events to promote whiteknot.org. When questioned about the knot, he responded, "You know what that's about? I believe in love and I believe in equality and I believe in marriage equality". Grohl's gay rights activism dates back to the early 1990s, when he and the other members of Nirvana performed at a benefit to raise money to fight Oregon Ballot Measure 9. "Measure 9 goes against American traditions of mutual respect and freedom, and Nirvana wants to do their part to end bigotry and narrow-mindedness everywhere," the group stated. The ballot measure was ultimately defeated on November 3, 1992. Grohl has also participated in two counter-protests against the Westboro Baptist Church for their anti-gay stance, once by performing "Keep It Clean" on the back of a flatbed truck and most recently by Rickrolling them.
