First, I think that the OP is confusing cause and effect; IMHO, the people who can’t run their lives without everything they do being dictated by their religion have been generally been crippled in that way by the religion which has infected them. Second; such people are a danger to themselves and others, since by definition they will do anything their religion asks of them - the OP implicitly assumes that religion is benevolent, and sane. And third, if they are truly that crippled they probably belong in an institution ( I expect that many such people do end up in one; prison ), not as the pawn of religion or as the sort of soldier who would not doubt massacre children if so ordered. It’s simply not healthy to be incapable of making your own decisions like that, or safe for anyone around you.
I would prefer that humanity be genetically modified to eliminate whatever mental defects cause religion. I regard religion as a mental disorder, not as a rational choice. And I do think that in the long run that either we will erase religion from ourselves, we will destroy ourselves under it’s influence, or religion will manage to drag humanity into a permanent Dark Age or a mind control based tyranny where it can utterly dominate humanity permanently. Religion is insanity, and it and a sane society are fundamentally incompatible; in the long run either it dies, society dies, or sanity dies.
