Last week, after Caitlyn Jenner introduced herself on the cover of Vanity Fair, prominent Iowa talk radio host Steve Deace told Republican candidates that if they wouldn’t speak out against Jenner’s transition, “you might as well just forfeit the 2016 election now.” When CNN’s Dana Bash asked Sen. Lindsey Graham about Deace’s comments in an interview over the weekend, he responded that while he’s “a pro-life, traditional marriage kind of guy,” Jenner is “welcome in my party.”

He then addressed Deace directly: “Here's what I would say to the talk show host: In the eyes of radical Islam, they hate you as much as they hate Caitlyn Jenner. They hate us all because we won’t agree to their view of religion. So, America, we’re all in this together.”

All of this, unsurprisingly, did not go over very well with Deace, who addressed Graham’s comments yesterday during his weekly discussion of presidential candidates with Iowa social conservative activist Bob Vander Plaats, saying, “If you’re not going to defend the idea of male and female, you’re not going to defend any of those other things that you just claimed to be for, Sen. Graham.”

Vander Plaats, an influential force in Iowa Republican politics, agreed, saying that if Graham wouldn’t speak out against people like Caitlyn Jenner, he could never fight radical Islam.

“The thing of it is, you can go out and you can have empathy and compassion for Bruce/Caitlyn Jenner,” he said. “However, you have to be able to stand up and say, but God still created us male and female. That’s the basic point here.”

“That’s our issue with Lindsey Graham,” he added, “is that you can say you’re pro-life, you can say you’re for God’s design for the family in marriage, you can say that he created them male and female, but when you never take a stand on those issues, it’s awfully hard for us to trust, then, that you’re going to take a stand against radical Islam or any other domestic matter or foreign matter that may come up during a presidency. That’s why I think in Iowa not many people take Lindsay Graham seriously.”
