Red equal sign spreads on social media in support of same-sex marriage

      The color of love is being used to make quite the statement online for gay marriage supporters.

      D.C.-based Human Rights Campaign launched the effort to turn the internet red Monday.

      It went viral.

      "It's just a statement of where we are as a people and where we want to be going that we believe in love, fairness and equality," says Anastasia Khoo, Human Rights Campaign marketing director.

      Outside the Supreme Court, with smart phone in hand, Andrew Rutkowski changed his profile pic to it.

      "I feel a lot of good stuff, a lot of love, a lot of people I didn't expect to post things like that did. A lot more people changed their facebook profile pictures, it's awesome," he says.

      Virginia U.S. Senator Mark Warner is one of at least 13 members of Congress who went red online supporting for gay marriage.

      Virginia Congressman Jim Moran did too - as did Maryland Governor Martin O'Malley.

      Ahead of Tuesday's Prop 8 hearing, Facebook found folks in D.C. buzzing about it most - people 25-44 have been the most engaged on the issue week.

      And Groupon posted a video of its employees who wore red.

      Outside the Supreme Court Wednesday, there were only a small number of people opposing same-sex marriage. Online, there's no viral protest. But some responded to other's posting pictures poking fun at the "Turn the Internet Red" campaign.
