LOS ANGELES, California (CNN) -- Protests continued Friday in several California cities, including San Francisco, Palm Springs and Long Beach, over the passage of Proposition 8, which outlaws same-sex marriage. The passage of California's Proposition 8, which bans same-sex marriages, has led to a number of protests. The ballot initiative, which passed 52.5 percent to 47.5 percent Tuesday, overturns a May ruling by the California Supreme Court that struck down a 2000 ban on same-sex unions. In San Francisco, an estimated 2,000 protesters marched down Market Street toward Dolores Park. The march stretched out for at least three city blocks, and the protesters completely blocked Market Street's westbound lanes and the eastbound lanes in places.
