Marriage Alliance spokesperson Sophie York put her proverbial foot in it during the secret meeting of groups opposed to same-sex marriage in Sydney last week, calling marriage equality supporters the "Pagan Caliphate" --which ruffled the feathers of Muslim leaders present.

The meeting on September 20 was due to be held at the Mercure Sydney International Airport Hotel, but it had to be moved because threatening phone calls were made to hotel staff. Instead the event was moved to another location in Sydney's CBD.
