Dave Grohl of the Foo Fighters is one of the first, and he wore it on the red carpet at Saturday night’s MusiCares benefit. So did musician Dave Stewart at the Grammies. Now its organizers are hoping Hollywood attendees and presenters wear it to the Oscars. It’s the “White Knot” in support of gay marriage. “The White Knot is the symbol for marriage equality. It takes two traditional symbols of marriage — white and tying the knot — and combines them in a simple way to show support for the right of gays and lesbians to marry. All loving couples deserve the same legal rights, benefits, and respect that civil marriage bestows,” say the organizers. Grohl, who is straight, told media Saturday night, “You know what that’s about? It’s ‘I believe in love and I believe in equality and I believe in marriage equality’.” The goal is to get White Knots on as many people as possible, keeping marriage equality in people’s (and the California Supreme Court’s) minds as the March 5th hearing gets underway determining Prop 8’s fate.
