Gareth Mclean shows that he has absolutely no idea about religion whatsoever:

By Rocco Buttiglione’s logic, David Morley got what he deserved. The once-aspiring EU commissioner believes homosexuality is a sin. The wages of sin, at least according to the book on which the Italian minister bases his morality, is death. Morley, a gay man who survived the bombing of the Admiral Duncan pub, was beaten up and left to die on London’s South Bank on Saturday. Ergo, the world is a better place today than it was last Wednesday.
You might think such an assessment crude, a reductionist cut-and-shunt of two separate circumstances related only by their timing. But the expression of bigotries such as Buttiglione’s creates an atmosphere in which hate crime, like that perpetrated against Morley and other gay men and women, flourishes. By labelling gay men and women sinners, Buttiglione degrades and dehumanises them, encouraging their abuse and assault. And he’s not the only one.

1) The Catholic Church, of which Buttiglione is an avowed member, does not base itself upon one single book. That is a rather more Protestant view. The Church is based upon the revealed teachings of that very Church.
2) One of those revealed teachings is that we are all, homosexual, heterosexual, abstinent, celibate, too tired to care and too drunk to notice, sinners. There is not one single sentient Catholic (although I suspect that Mr. Mclean would argue that one cannot be both Catholic and sentient) who would call for the death of sinners for to do so, by the most basic teachings of the Church, would be to call for the extermination of the human race.

So I fear that is argument is something of a stretch. As a bolster to my view, that the Church does not call for the death of sinners, I would point to the Pope’s, and therefore the Church’s, well established views on the death penalty. Agin it in almost every circumstance, even for multiple murderers caught red-handed in a welter of the gore and blood they spilled. That just doesn’t sound like a group or a viewpoint that urges death upon sinners.
