People with plenty of food, shelter, internet, etc may have no need for a god, but why the lack of tolerance to those that for whatever reason do need a god to believe as they wish?
Is it healthy for kids to retain an imaginary friend as they grow older, and increasingly believe that that imaginary friend directly influences their life and the surrounding world? Even to the point of basing real-world decisions off of what they think this imaginary friend wants them to do? (Just do what the voices tell you.)
What if they start listening to what someone
else's imaginary friend is saying?
Or, a potentially dangerous example: Earth has been hit by large asteroids in the past, and small ones too. There was just the Tunguska Event in the early 1900s. The only thing that helped us out is that our planet has a lot of uninhabited area as a percentage of its total surface - it was just random chance that it didn't flatten a large populated area. The recent one that blew up over Chelyabinsk (fun one to spell right there) was another close call.
There are a few hundred thousand potentially dangerous asteroids in our orbital neighborhood.
If you're full into the "god has a plan for us/god loves us/god is benevolent" thing, then you may be prone to believe that none of these things will ever pose a threat, because your god won't
let it happen. (Or maybe he will, because he might feel like punishing people because he sometimes totally loses it. At least he promised he wouldn't genocide us again using
floods.) So you might therefore not want to invest anything at all into asteroid mitigation efforts. That's already got an uphill battle simply because the statistical interval of asteroid impacts is a good bit longer than a human lifespan, therefore "It probably won't kill
me, so I don't care" is the usual mindset.
It's something that has a low chance of happening in your lifetime, but a high chance of happening
period, and very serious consequences when it does happen.
