Buahahahah!
Well, she's not wrong.

When people try to convert me, I ask them if they've felt the might surge of Zeus' lightning, the Eagle from on high whom watches over us from Mt. Olympus.
They think it's silly. I tell them it's even sillier that they don't even have a statue of what their God looks like.

If I ignore that there are proper definitions of what "mentally-ill" means, personally, I think it is equally crazy and bizarre for an adult person to talk to non-existing mythical beings and hearing them talk.

I agree that LITERALLY hearing voices reflects a form of mental illness. The level at which most believers claim to "talk with" god is no different than a child with their imaginary friend, it is just a personal / group fantasy role playing thing.

here in UK we have Hearing Voices Networks where people get together who are voice hearers - not everyone feels they have anything to heal and don't get destructive voices but those who do can get help for what to do, I have D.I.D and occasionally hear voices , but my alters are pretty quiet these days I imagine because I am less tuned in - being a lot older.

You all sound as if you think all voices are religious I know no-one who gets messages from god some of the messages are helpful like your shoelaces are untied.

If I really believed a person was mentally ill, deliberately trying to anger them would seem unkind at best, and maybe a sign of mental illness on my part. If I really didn’t think the person was actually mentally ill but called them that because they held beliefs different from my own, I would think that my debating skills were lacking.

There is mounting scientific evidence suggesting that “hearing voices” is an evolutionary adaptation; not the voice of an actual god, but also not a sign of mental illness. At any rate, it, in itself, seems harmless enough. I worry more about people who think it’s admirable to generate war for profit.

Perpetuating memes that demean a class of fellow humans for their beliefs seems indistinguishable from what we’re often complaining about ourselves; being treated unfairly because of our worldview.

Somebody asked me if I had accepted Jesus Christ as my Lord and Savior? So I said, I talked to Jesus yesterday and he told me to tell you, it's none of ya damn bizzyness!

If you want to call delusion a mental illness...lmfao
