That MUST be Gary North, the famously whacked American Fundie. He used to be a favorite on Art Bell's radio show, which you have probably read about it in here.
Another Gary North is an American journalist, but he's not likely to be involved with the Fundies - according to Wikipedia, that Gary North is "currently the president of the bisexual civil rights organization BiNet USA."
North passes himself off as an economist and scientist. If he ever had much credibility, it took a huge whack during Y2K when he went around predicting the downfall of civilization after all the computers crashed etc.
A flashback to those glory days, from an old news story:
The Arkansas-based North, who declines interviews, has prompted much of the Y2K influx to the region. Presiding over a vast Internet system, North is a religious "reconstructionist" who thinks society must collapse before Jesus Christ returns. He's also into goldbuggery and all the usual obsessions of his ilk:
