Some people have a deep rooted need to believe.
Wether this is through nurture or nature I do not have the answer.

Vote: None of the above. Religions are belief systems given credence by the mentally infirm.

I'm with Freud.

All religious belief systems entail the existence of supernatural beings which is one valid definition of insanity.

How is truly blind faith NOT a type of mental disorder?? I'll never get why there aren't more of us out there.

If could, I'd move to Iceland.

Religion is a meme, in its original defintion: "an idea, behavior, style, or usage that spreads from person to person within a culture." It is a mental virus that evolves and impacts the hosts. It becomes a mental disorder if (or when) it negatively impacts the host or those around them.

Choosing to ignore facts and believe something that cannot be demonstrated in any meaningful way is a mental disorder.

There's a danger in these satirical publications, because those who are willfully ignorant never read beyond the headlines and pass it along as fact. I had to educate someone yesterday on facebook that Pelosi did not take millions from Social Security to pay for the impeachment proceedings. That article also appeared in a satirical publication.

Lol funny

It’s simply not true.

65% of Icelanders belong to the Church of Iceland, though many are members in name only.

I applaud Iceland and Sweden for their principled and enlightened stands.
While I don't see religion as necessarily a "mental disorder," in some of it's myriad forms (fundamentalist Christianity, jihad Islam, etc.) it most certainly IS deranged and potentially harmful especially to vulnerable, impressionable, and/or developing minds.
