This is meant to be a general question, but I will begin be prefacing it with that this being motivated by Scientology, in particular. The broad question is at what point does something drift from being a religion, and viewed as something that is, in effect, a personal choice, into something that should be thought of and addressed in a different manner? Generally, with freedom of religion, that leads to that one can choose to believe and worship what one wants, and within reason, the manner one wants to. However, are there points where this freedom should be stripped, based off the basis or goals of those ideas? Further, is it still a religion at that point, or does it represent some sort of ideology or ism or conspiracy at that point? To look at a case in particular, I've been recently reading a book called "Inside Scientology" and one of the points that it discusses is how the church, as an official action, infiltrated or stole from over 100 organizations in an attempt to purge any information that was critical of them. When the church begins to carry out systematic, organized attacks against the government, do they now represent a political movement that is taking part in sufficient conspiracy that it warrants the government trying to shut them down or stop them? The possibly related question is, are they still a religion at that point? What boundaries are there for what is or is not a religion, as well as for what is or is not a group conspiring against the public good and the government?
