Your first statement about Senators is a rhetorical statement. It isn’t meant to be believed. If they were actually mentally delusional, they would not be in office."Delusional:.
1.having false or unrealistic beliefs or opinions: Senators who think they will get agreement on a comprehensive tax bill are delusional.
Psychiatry. maintaining fixed false beliefs even when confronted with facts, usually as a result of mental illness: He was so delusional and paranoid that he thought everybody was conspiring against him."
"A delusion is a belief held with strong conviction despite superior evidence to the contrary. As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, or other effects of perception".
"When one person suffers from a delusion, it's called insanity.
When many suffer from a delusion, it's called religion."
...Robert M. Pirsig
I stand by my statement.
Adults who have an imaginary parent/friend are suffering from a delusion.
They reject reason because they wish to believe a fantasy and that is irrational.
Are you trying to say that they are just "confused" or "mistaken?"
As for your second point, again, you are talking about something very different. There is not a Psychiatrist in the world who would say that Christians have any sort of mental illness because they believe in God.
All of your definitions are defining clinical diagnoses of individuals, not a mass amount of people. The evidence many of them have is very concrete (historical records for instance) despite your inability to accept that. You believe many concepts and or events you cannot verify yourself such as the Moon landings. Sure there are writings on it, but so are there writings about Jesus with physical places and things related to events. But you have never been to the Moon and you never actually saw it happen. Yet you and many others believe man walked on the Moon. Are you delusional? And yes, there are many people who will and have claimed the Moon landings were faked.
None of your arguments would hold water with any Doctors when considering why people as a whole believe in God. Not one of those people could be clinically diagnosed as delusional because there is much more to that illness than simply accepting or believing in a single aspect of life. You are kicking a dead horse. Find me some psychiatrists that agree with your argument, or you've got nothing.
