I know the show you are talking about. They are a bunch of atheists and agnostics who have immersed themselves in proving to the world how 'irrational' Islam is. The overall conclusions they come to are almost always against Islam. That would have been not a problem if they bring an equal lot of well educated Muslims arguing for Islam to engage in discussion and letting the viewers decide. They usually allow one Muslim and they are usually four to five in total arguing against. And they would then spend the next three hours arguing with the person about how Islam is irrational. They employ sarcasm, mockery, subjective views with some objective research and present Islam as an unreasonable ideology. They also attack from multiple angles making a single topic of discussion difficult.
