Recovering from pneumonia, George Michael took to Twitter yesterday with a characteristically colourful series of messages slamming a little-known fundamentalist organisation which told people to pray for his death.

The singer, who returned from a month-long stay in an Austrian hospital just before Christmas, had spoken of how doctors on the continent were “keeping him alive” after he came down with the condition.

But at least one religious organisation was praying for his death and suggesting the illness was AIDS-related, a claim was refuted by doctors.

Last night, Michael criticised their use of religion as a “pathetic excuse” to call for his death, while praising the “wonderful, kind hearted” Christians he knew.

Michael said last night: “Did you know that while I was fighting for my life in Austria there were a bunch of those lovely American ‘Christian’ organisations, who call themselves “Christians for a Moral America”,who were actually taking the time to pray for me to die…”

“How very sweet of them, considering how busy they must be on the whole. Now don’t get me wrong, I know for a fact that many devout christians, such as the ones I work rest and play with on a daily basis, are truly wonderful, kind hearted men and women who take the best parts of that religion and live admirable, generous and loving lives.

“But In my opinion, and i think made evident by those who prayed for my death, there are others who use their twisted interpretations of ancient scriptures as a pathetic excuse to be…….wait for it, wait for it…….! Totally fucked up cocksucking bastards.”

While Michael was hospitalised, one member of the group known as Keith, posted messages on Twitter including: “Apparently George Michael has AIDS. Figures since he’s a homosexual and it goes with the territory. Another sodomite bites the dust?”

Posting under the username @godswordislaw, which has 7,500 followers, he also wrote: “Pray for George Michael’s demise. He has chosen a satanic lifestyle and must meet an appropriate end.”

In late November, when Michael was diagnosed with pneumonia, the group’s blog said: “It’s almost symbolic that just after the 20th anniversary of Freddie Mercury’s death from AIDS that another famous homosexual would succumb to this disease.

“We pray that George Michael has found salvation through Christ in his last days otherwise he will pay for his unrepentant lifestyle in hell.”

The Christians for Moral America blog lists liberals, atheists, gays, Muslims and feminists as the most dangerous anti-American groups of 2012.
