(CNN) Democratic presidential candidate Elizabeth Warren was met with loud applause at CNN's LGBTQ Town Hall in Los Angeles on Thursday when she joked about a potential faith-based argument against same-sex marriages.

Morgan Cox, chair of the Human Rights Campaign Board of Directors, asked the Massachusetts senator how she would respond if an "old-fashioned" supporter told her that they believe marriage is between one man and one woman.

"I'm going to assume it is a guy who said that," Warren started. "And I'm going to say, 'Well, then just marry one woman. I'm cool with that.'"

She then paused and shrugged before finishing her joke -- "Assuming you can find one" -- with a deadpan delivery that sent the crowd into loud applause.

Warren later reflected on how faith influences many people's beliefs towards the LGBTQ community, including her own, and recited the first song she remembers learning as a child in Oklahoma.
