Today, I am participating with friends, and my girlfriend, to march in DC's protest against California's Prop 8, where the voters chose to "eliminate the right of same-sex couples to marry" (the actual California government's words, not the advocates, and not mine).
Want to protest in your city? There's already one going! Just look up your city on Join the Impact. (scroll down a bit, look to right)
Gay, straight, bi, trans, get out and shout: "LOVERS OF THE WORLD UNITE!"
