Fox News guest Lars Larson on Monday blasted Mary Cheney after she and her same sex partner posted on Facebook that they had been insulted when sister, Liz Cheney, told Fox News that they didn't deserve marriage rights.

“I love Mary very much, I love our family very much,” Liz Cheney insisted to Fox News host Chris Wallace on Sunday. “This is just an issue on which we disagree.”

Within hours, Mary Cheney and her partner, Heather Poe, had taken to Facebook to explain their side.

“Liz – this isn’t just an issue on which we disagree, you’re just wrong – and on the wrong side of history,” Mary Cheney wrote, according to The New York Times.

“Liz has been a guest in our home, has spent time and shared holidays with our children, and when Mary and I got married in 2012 – she didn’t hesitate to tell us how happy she was for us,” Poe added. “To have her say she doesn’t support our right to marry is offensive to say the least.”

“I can’t help but wonder how Liz would feel if as she moved from state to state, she discovered that her family was protected in one but not the other.”

On Monday, Fox News host Gretchen Carlson noted that former Vice President Dick Cheney and his wife, Lynne, had released a statement saying they had dealt with the situation "privately for many years" and called for compassion.

"That's exactly where it should stay, it should stay private," conservative radio host Lars Larson agreed. "And what I find disturbing about this, I have friends of 40 years who are gay. I don't care. What they do in their own bedroom is their business. When you bring something to the public sphere and demand that government acknowledge, sanction and endorse gay marriage then there are going to differences."

"I think it's sad that Liz Cheney's sister has chosen to make this a public fight to damage her sister's political ambitions," he continued. "And to do it in a way that doesn't respect Liz Cheney's personal beliefs or personal values."

"We hear a lot about personal values from the left. And yet it sounds like as far as the gay agenda goes, it's take no prisoners and yes is the only answer. And if you don't agree, we'll do everything we can to hurt you."
