Margaret Hoover and Madeline Koch are among the conservatives joining the gay marriage group Young Conservatives for the Freedom to Marry, which is launching today in Washington D.C.

According to a press release, members of the group will work to “encourage more conservatives to stand up, speak up and support the freedom to marry by joining and adding new perspectives and experiences to the national conversation about marriage.”

The group will also work to approve gay marriage laws and repeal the Defense of Marriage Act (DOMA), the 1996 federal law which defines marriage as a heterosexual union.

“Freedom and family are core conservative values,” Hoover said. “We have a historic opportunity to reaffirm these important values by supporting the fundamental freedom to marry for all Americans. Now is the time for a rising generation of voters and leaders to embrace these virtues and join Young Conservatives for the Freedom to Marry.”

“The more we think and talk about this with other conservatives, the more we can understand why the denial of marriage to same-sex couples is wrong,” said Torrey Shearer, a member of the group's leadership committee. “Marriage strengthens families, encourages shared responsibility, and promotes stability in our communities. There is really significant change taking place among conservatives – especially young conservatives – about the freedom to marry, and I hope my involvement in this campaign will accelerate our progress.”

Also on the Young Conservatives for the Freedom to Marry leadership committee is Madeline Koch, whose testimony before a Minnesota Senate committee hearing considering a gay marriage ban went viral last year.
