According to the Pope:
Pope Benedict XVI on Thursday called abortion and same-sex marriage some of the most "insidious and dangerous" threats facing the world today, asserting key church teachings as he tried to move beyond the clerical abuse scandal.
Benedict made the comments to Catholic social workers, health providers and others after celebrating Mass before an estimated 400,000 people in Fatima. The central Portuguese farming town is one of the most important shrines in Christianity, where three shepherd children reported having visions of the Virgin Mary in 1917.
The only proper answer is a YouTube song which is NOT safe for work! It might not even be safe for home!
A more polite response might be to note that Benedict XVI himself is insidious and dangerous. To children, women and all growing things. So.
