Other attractions in the 10-day festival include parties, an open-air market, gay-themed films, an ice skating rink and religious services on Dec. 25.

ProGay group chairman Frank van Dalen said Monday the event is intended to increase the choices for homosexual men and women during the Christmas holiday week.

“Right now, there’s not much to do,” he said.

The festival will also encourage people to think about homosexuality and religion, Van Dalen added.

Some Christian groups protested. The organization Christians for Truth said the idea “mocks the core concepts of Evangelism.”

“By putting Joseph and Mary down as homosexuals, a cracked human fantasy is being tacked on to history from the Bible,” the organization said in a statement urging the city and organizers to cancel the event.

The manger, with actors playing the parts of Joseph and Mary, goes on display Dec. 21.

Van Dalen said it was not intended to be offensive, but was meant as a “wink” at heterosexual assumptions.

“Christmas is about more than religion, it’s also about love and families, not to mention shopping,” he said. “Two men or two women can form a family too these days, even one with a child.”

Gay marriage was legalized in the Netherlands in 2001, and adoption rules are the same here for gay or straight couples.

Van Dalen said the Pink Christmas initiative was also intended to help promote Amsterdam as a gay capital after a decline in its reputation in recent years.

A study last month found that homophobia is an ingrained problem in the city despite the Dutch reputation for tolerance, and physical attacks on gay men are a weekly affair.

The Groningen District Court found the two guilty of severe assault for injecting semiconscious men with HIV-infected blood at sex parties between January 2006 and May 2007.

Peter M., 49, who was also convicted of rape, was sentenced to nine years in prison and Hans J., 39, received a five-year sentence. Under Dutch privacy laws, the surnames of convicted criminals are not released.

Prosecutors said they would appeal for higher sentences.

“By committing these acts, (Peter M.) has shown himself to have a serious lack of respect for the rights of others,” the three-judge panel’s written ruling said. “While he knew from his own experience what far-reaching consequences are tied to an infection with HIV, he repeatedly attempted to bring this same hurt to others.”

Prosecutors had argued that the two men, along with a third who was acquitted of major charges, had drugged the 14 victims and intentionally infected them.

But in Wednesday’s ruling, judges said while the victims all had HIV, it could not be proven that they were infected by the injections because they willingly took part in orgies where gay men unprotected sex.

The judges also said allegations the victims were given GHB, known as a “date rape” drug, were also unproven.

The suspects were not charged with attempted murder since Dutch courts have held that HIV is a chronic illness rather than an inevitably fatal one.
