When Christians make empirical claims about things they generally only need to back them up with scripture or church teaching. The further the claim is from the actual evidence the more faith one needs to fill it in. It’s not a level playing field. An emotionally stunted person from a rough background who had zero experience of God is going to have a tremendous amount of faith to function in religion. A person with a normal life with normal emotional function will need less faith.
The thing about religious people is they so badly want to capture that token minority to further their aims. They want a disabled person who will parrot the Christian talking points on suffering (romanticizing it) because it makes the view seem more authentic if it’s coming from an actual member of that minority.
