I'll let you hear for yourselves what he claims some of the actors on the show were into...
Well, who knows if this guy really ever participated in what he claims took place, but some of the actors have mentioned in a few print interviews that what he claims did actually happen at certain parties. (So it could be that he's simply repeating stuff he'd read.) But were they serious about it? Well, that's not the impression I ever took away from what I've read.
As for this guy himself, his rhetoric reminds me of a person who, along with his wife, has a national program on which he's been claiming the "End of Days" is upon us for more than 15 years already. (I haven't watched him in several years, but his show is one of the most unintentionally funny on the air that you almost can't resist tuning in.) He's repeatedly gone so far as to say exactly what year certain events are "definitely" going to take place. Funny thing about that, though - when those years come and go without his predictions ever coming to pass, he always has a convenient excuse as to why that was - in spite of the fact that he'd previously spun such elaborate scenarios as to why they were "definitely" going to take place!
Heavens save us from these types. And don't even get me started on how much they hawk their own video/audio tapes that the "faithful" should be buying from them so that they can learn more "in greater detail" than can be covered on these people's programs. If you ask me, with probably little exception, many of these types are actually far worse when it comes to preying on their followers beliefs and fears than the people they preach against...
