A travelling anti-gay marriage prayer rally will go ahead as planned in Brisbane this Thursday despite a dramatic counter-demonstration in Lismore at the weekend that saw residents chain themselves to the protest truck.

Christian Democratic Party candidate and anti-gay marriage protest leader Peter Madden awoke yesterday to find his campaign truck defaced and blockaded amid claims he was vilifying homosexuals.

But Mr Madden carried on with his mission to protest in Brisbane after New South Wales police used saws and bolt cutter to remove two protesters who had chained themselves to the truck by the neck.

The Stand for Marriage Queensland Election Prayer Rally Tour was at the Gold Coast this morning when Mr Madden spoke to brisbanetimes.com.au.

“We will be in King George Square on Thursday,” he said. “We could get as little as 200 or as many as 1000 people turn out in support.
