As snow falls in Washington, DC, dueling rallies are taking place outside the Supreme Court today as the justices prepare to hear arguments in the contraceptive mandate case involving Hobby Lobby.

Supporters of Hobby Lobby are leading chants like "Religious freedom is everyone's business" and "Real healthcare respects life." They even have a bagpiper playing songs like "Amazing Grace."

On the Hobby Lobby side, chants of "religious freedom is everyone's business" and "faith, family, freedom" pic.twitter.com/blFWZbp7dF - Betsy Klein (@betsy_klein) March 25, 2014

On the other side is a much larger group organized by Planned Parenthood, NARAL Pro-Choice America and other groups supporting the contraception mandate. They are leading chants like, "Hey, Hey, birth control is here to stay" and "pro-family, pro-birth control."
