After so-called expert Steve Emerson told Fox News that Birmingham was "totally Muslim", the broadcaster decided to calm the resulting storm by inviting on Nigel Farage to set the record straight on how "Sharia law" was being applied in UK "ghettos."
The Ukip leader appeared with host Sean Hannity, who opened the segment saying: "Multiculturalism is in fact to blame for the tragic events last week in France".
Farage told Hannity, one of the channel's most prominent and aggressively right-wing hosts, that our "moral cowardice" had seen us turn a "blind eye" to "the growth of ghettos".
The host asked which European countries had allowed "Sharia courts" to come in.
Farage replied by condemning the failure to prosecute people in Britain for female genital mutilation and claimed women had been allowed into the UK "from Pakistan and elsewhere to join polygamous marriages".
"Wherever you look you see this blind eye being turned and you see the growth of ghettos, where the police and all the normal agents of the law have withdrawn and that is where Sharia Law has come in," he said.
"Do you know, it got so bad that our last Archbishop of Canterbury, the leader of our church, actually, actually said we should accept Sharia law."
This refers to comments by Rowan Williams in 2008, when he said: "As a matter of fact certain provisions of sharia are already recognised in our society and under our law".
The Twitter reaction to Farage's comments on Monday night was predictable, with one Tweeter calling him "the patron saint of normalising racism as common sense".

Farage also fanned the flames of Emerson's incendiary claims about "no go" Muslim areas - agreeing with Hannity's claim that they were places "the police are not allowed to go, non-Muslims are not allowed to go".
Hannity asked: "Why would France, or another other country, allow Muslims who have come into the country to basically take over portions of that country? It seems like madness to me."
"It isn't just France," Farage said. "We've got no-go zones in most of the big French cities, we’ve been turning a blind eye to preachers of hate, that have been coming here from the Middle East and saying things that the rest of us would be arrested for."
He also raised the child abuse scandals in Rochdale and Rotherham, saying: "In parts of Northern England, we’ve seen the sexual grooming scandal of underage girls, committed by Muslim men in the majority.
"And for all of these things we’ve seen the law not being applied equally, we’ve seen the police forces not actually doing their job, because we’ve suffered from moral cowardice."
"We have through mass immigration and not checking the details of those people coming in... we have allowed big ghettos to develop and when it comes to confronting big issues, we run a mile.
"That's why we're in the mess we're in. We've been led very badly."
Hannity asked: "Why would Great Britain, France, Belgium or any other country, the Netherlands, why would they allow people to come to the country, not assimilate, separate, take their land ostensibly and risk even being at war with them when sharia, if you're coming from a country that you grew up under sharia, those values directly contradict the values of Western countries, why would anybody allow that?"
Farage said: "Well Sean, I agree with your sentiments entirely, but we have a political class that is leading countries in Europe, hopelessly out of touch with the real world."
Farage's comments on "no go" areas also attracted derision on social media, with people calling the claim "complete bollocks" and accusing him of "fuelling" the controversy.
Nigel Farage went on Fox News last night to fuel the "no-go zones for non-Muslims" thing, by the way: http://t.co/PtsFU5obhn— Jon Swaine (@jonswaine) January 13, 2015
