Conservative commentator Andrew Bolt has branded the leader of an anti-Islam protest "extremely rude" and demanded an explanation for why he and a group of others donned Arabic-style dress and walked into a Gosford church on Sunday, interrupting its service.

Nick Folkes, the leader and spokesman for the Party For Freedom, appeared in a tense interview on The Bolt Report on Sky News on Monday night to talk about the stunt at Gosford Anglican Church where the group placed prayer mats on the ground and used a loudspeaker to shout slogans.

At the beginning of the interview, which was abruptly cut short when Folkes' microphone was silenced, the broadcaster asked: "Please explain to me why you were so damn rude."

Folkes responded: "I don't think it was that rude, Andrew, I think that the point needed to be made. It was disruptive for some people ... there's always going to be people that do take offence."
