Are There Different Types of Delusion?

We are all subject to delusional thoughts to some degree and at some times in our lives. Ironically, the expression "to show one's colours" could be construed to mean that one is hallucinating whilst being under extraordinary pressure.

However, this is a forum on religion and we are looking at delusion in that context. Just like delusion there are varying degrees of religiosity and most people who claim to be religious do not believe there is a God, religion to them is just a cultural or social convenience or, in some cases, a tool used to manipulate others. As we all (should) know, anyone who fervently believes in God is deluded; the point has been debated in this forum ad infinitum over the years and the fact has never been successfully challenged.

What we are talking here though is the differences in delusion; in particular, those who are deluded by their own choosing and those who have delusional beliefs forced upon them. It could well be argued that many people who, say, go to church in a modern, civilised society and start believing in God did so because they are impressionable, naive and gullible and were coerced by those in authority, i.e. the clergy. For the sake of distinguishing between two different types of delusion, let's accept these people as being deluded by their own choosing, they, after all are responsible for their own psychological well-being.

But what about religious followers who live in other countries who must believe in God otherwise they will be decapitated. They have little, or no access to truthful media and know no different, in fact they are so profoundly deluded they fear the earth upon which they walk. Is the delusion that they suffer different to the delusion commonly experienced by others of their own choosing?
