Worse than the terrible tragedy at Columbine High School is the refusal to learn from what happened. The two killers, Dylan Klebod and Eric Harris, were admirers of the Satanic rock singer, Marilyn Manson. The Trench Coat Mafia, taking after Manson, also adored Hitler.

“They sing Marilyn Manson songs and joke about killing people.” That was how one of the Columbine students characterized the killers. “They’re really into Nazis. They take pride in Hitler.”

The connection between Manson and Hitler and the Trench Coat Mafia is this: evil is the driving force. That is why Manson entitled one of his albums, “Antichrist Superstar”: his goal is to convey the message of evil.

“I am so Anti-American, I’d sell you suicide/I am totalitarian, I’ve got abortion in my eyes.” That is what Marilyn Manson sings about. He also sings about suicide. And, of course, he has gone out of his way to attack Catholics.

Now compare this to what the two killers put on their website: “What I don’t like, I waste.”

The experts tell us that parents and teachers need to take serious certain “warning signs” that are useful for spotting troubled kids. Among them are the following: joining a clique of weird kids; sporting swastikas, skulls and gravestones; listening to music with satanic or violent lyrics; obsessing with the occult, warfare or gory video games; self-mutilation, such as sticking safety pins in the ears, or excessive body-piercing, etc.

The saddest part of all is that there are millions of parents and teachers for whom such knowledge would be a revelation.

Look for things to get worse as we get closer to the year 2000: the crazies will be coming out of the woodwork.
