I think Christianity (at least in the US, probably elsewhere, too), particularly fundamental/evangelical Protestantism, has, for a long time, welcomed into its fold all manner of kooks, cranks, quacks, and charlatans. For the most part, these folks have managed to stay mostly outside of the greater public consciousness despite having huge followings within the evangelical community. Fundamentalism built for itself this parallel culture almost entirely separate from the mainstream and it seems to me that both people inside it and outside it were content to keep them separate. We've long passed the point where the influence of these kooks is limited to their own flocks; their influence and harm extend well outside of their groups via their ability to wield persuasive power over the people within their groups and the influence those insiders have on the rest of society. I think Christianity needs to purge itself of these kooks - both for its own sake and for the sake of the population at large; and I don't think that purging can happen without significant outside pressure shining a light on just how nutty and wrong so many of them are.
