Hollywood is sick, sick, sick. Behind its curtain of holier-than-thou progressivism, the entertainment world's top A-list stars have engaged in the most depraved sexual abuse against vulnerable children and teens, according to a growing number of victims. After years of cover-up, the institutional scandal is exploding. Finally.

The latest alleged atrocities involve "X-Men" director Bryan Singer and at least three other power players in the business: veteran television executive Garth Ancier, former Disney executive David Neuman and producer Gary Goddard. Last month, former child actor and model Michael Egan filed civil suits against the men, alleging that they passed around underage boys "like pieces of meat at sex parties" in the late 1990s. Egan's X-rated lawsuit exposes a cabal of alleged predators who plied young boys and teens with hard drugs and alcohol before sexually assaulting them.

Egan was repeatedly molested, raped and beaten from the age of 15, he says, at an infamous gay sex mansion in southern California. The mansion was owned by another of Egan's alleged abusers: scumbag Internet video mogul Marc Collins-Rector. He's a registered sex offender who lured young boys online, drugged and raped them, and reportedly threatened them with a gun if they did not submit.

Collins-Rector was convicted in 2004 of transporting five underage boys across state lines with the intent of raping them. He was allowed to leave the U.S. in 2006 by claiming a "brain tumor," according to The Hollywood Reporter. The (U.K.) Sun reported in 2007 that he was "swanning around Britain in a chauffeur-driven limo and surrounding himself with young boys." He can no longer be located, despite supposedly being under police "supervision."

Egan's mother reported the abuse to the FBI and Los Angeles Police Department back in 2000, the family's lawyer, Jeff Herman, says. Nothing was done.

Singer's lawyer calls Egan's suit "absurd" and "defamatory." But the allegations just keep piling up. Singer is now the subject of another lawsuit filed this week by a young British man who alleges Singer's producer pal Gary Goddard groomed him online from the age of 14, raped him at 16 and shared him with Singer after the London premiere of Singer's movie "Superman Returns" in 2006. Internet photos have been circulating for years showing Singer with a parade of young boys and men draped around him.

Egan's claims are especially chilling in light of similarly lurid allegations made 17 years ago on the set of Singer's movie "Apt Pupil." Three underage boys—ages 14, 16 and 17—filed suit claiming Singer and his crew forced them to take off peach-colored G-strings and strip naked in a shower scene for the movie. Authorities investigated. The suit was dismissed. Nothing was done.

"Everyone's ducking for cover," Paul Petersen, a former child actor and child actors' advocate, told Entertainment Weekly in 1997. "It's a complete and total breakdown of the protections Hollywood pretends it accords children."

The same industry that sanctimoniously convenes anti-bullying summits with the Obama White House and falsely accuses conservatives of waging a "war on women" has allowed countless children to be stalked, groomed, beaten, molested and raped on casting couches, in movie trailers, and at drug- and alcohol-drenched parties by Tinseltown predators. The alleged child rape scandal exposed by Egan does not exist in a vacuum:

• Last year, child actor Corey Feldman sounded the alarm on rampant pedophilia in a brave, scathing memoir. He recounted how his best friend and co-star, the late Corey Haim, was sodomized by an older male on the set of their hit film "Lucas." The boys, fed cocaine by a string of predators, attended parties with Hollywood talent manager and child actors' rep Marty Weiss. Now a registered sex offender, Weiss pleaded no contest in 2012 to lewd acts on a child under the age of 14. The victim, another young child actor, alleged Weiss sexually assaulted him between 30 and 40 times from the age of 11.
• Registered sex offender Jason Murphy, a Hollywood casting agent, had kidnapped and molested an 8-year-old boy before joining the industry.
• Boy band impresario Lou Pearlman was a con artist and sleazeball who hosted sleepover parties wearing only a towel and solicited massages from young male singers. "Certain things happened, and it almost destroyed our family," boy band star Nick Carter's mother told Vanity Fair years ago. "I tried to warn everyone."
• Former child actor Todd Bridges, of "Diff'rent Strokes" fame, says he was abused by his agent.
• Former teen pop princess Debbie Gibson has spoken of "older male record executives" who hit on her while she was still underage.
• Despite disturbing and longstanding allegations of molestation and rape, directors Woody Allen and Roman Polanski still enjoy professional acclaim and adoration of their peers.
• Perv fashion photographer Terry Richardson continues to enjoy the support of Lady Gaga, Beyoncé, Rihanna and Miley Cyrus despite years of allegations of misogyny, manipulation and sexual misconduct against young models.

If all of these sickos had been Catholic priests, college fraternity members or charter school teachers, we wouldn't have heard the end of it. Perhaps the social justice awareness-raisers in the Hollywood left should take a break from pointing fingers at everyone else—and put a stop to the monsters in their own midst.
