Keith Allen has never been the sort of bloke to back down from an argument, but in his recent Channel 4 documentary, "Keith Allen Will Burn in Hell", it looked like he'd finally met his match.Covering similar ground to Louis Theroux's BBC offering, "The Most Hated Family in America", Keith met members of Westboro Baptist Church, the home of America's most fanatical Christian fundamentalists.During his three days at Westboro, the actor, songwriter and director exposed the strange mixture of hatred and happiness that runs through their faith.More importantly, he also discovered that the church's chief spokeswoman, Shirley Phelps-Roper, has an illegitimate child, a fact that she's very keen to hide.Allen uses that fact to question her beliefs, but despite what he sees as the contradictions in her preachings, she doesn't admit defeat so easily.So take it away, USA. Remind Shirley Phelps-Roper of her hypocrisy at every opportunity, and remind her bastard son exactly where he came from - and that according to their creed they can be secure in the knowledge that they now know exactly where they're headed.
