Stephen Colbert brutally mocks anti-refugee GOP candidates: Are they Christians or terrorists?

Stephen Colbert harshly rebuked Republicans who are refusing to allow Syrians to seek refuge in the U.S. from their nation's brutal civil war.

The U.S. House of Representatives overwhelmingly passed the GOP-backed American Security Against Foreign Enemies Act -- or ASAFEA -- to suspend Obama's program to admit 10,000 Syrian refugees in the next year and then intensify the process of screening them.

"Under the law (ASAFEA), no one with a name like that will be allowed into the country," Colbert said.

He mocked Donald Trump, the presidential frontrunner, for suggesting that Syrians accustomed to "130-degree" temperatures would become angry if they were forced to live in colder climates, such as Minnesota.

"Yeah, it's a tough call for the refugees -- do I want to stay in a war zone where my family faces almost certain death, or do I want to go somewhere where I have to put on a jacket before I go to the mall?" Colbert said.

Every single Republican presidential candidate has spoken out against accepting Syrian refugees, and President Barack Obama ridiculed them for being as afraid of "widows and orphans" as they are GOP debate moderators.

"I don't think the president is being entirely fair here -- it's not the little kids that concern the candidates, it's adults who might come also," Colbert said. "But since you brought it up, Mr. President, why shouldn't we be scared of 3-year-olds? You think you can't negotiate with terrorists? Try negotiating with a 3-year-old. They play hardball."

Two candidates, Jeb Bush and Ted Cruz, have suggested limiting refugees to Christians only, saying that "there is no meaningful risk of Christians committing acts of terror."

"That's right, Christians have never committed acts of terror," Colbert said, showing a photo of Ku Klux Klan members rallying around a burning cross. "I'm sure these guys right here are just campers roasting marshmallows. You can tell they're campers because they're each wearing one-man tents."

Bush insisted that refugees should be able to easily prove they're Christians, but he simply shrugged and repeated himself when asked exactly how they would do that.

"If you want to know if somebody is Christian, just ask them to complete this sentence," Colbert said, quoting from Matthew 25:35. "Jesus said I was hungry, and you gave me something to eat. I was thirsty, and you gave me something to drink. I was a stranger and you -- and if they don't say welcomed me in, they are either a terrorist or they are running for president."
