People on Facebook and Twitter have been changing pictures and avatars en masse to an image of a red equal sign. You've probably noticed. But why?
The Human Rights Campaign, which advocates for equal rights on behalf of LGBT Americans, has been promoting the image in lieu of its usual blue-and-yellow logo.
A symbol of "equality, it's part of an effort to mobilize supporters online with Supreme Court hearings on gay marriage underway in Washington, D.C.
The simple photo of the equal sign has racked up more than 25,000 “likes” and 78,000 “shares” on the group’s Facebook page in the last 24 hours alone.
