I can believe I’m going to get eaten by a talking meatball when I go to dinner tonight.
The talking meatball obviously isn’t going to eat me, it isn’t real.
The impact the talking meatball has on my decision making remains a real observable thing.
Nobody is blaming god here, they’re blaming the concept of god/gods, and how that concept has resulted in many people treating others poorly.
Note, that’s not a judgement on you (presumably) having beliefs, I believe there’s probably something out there myself. The talking meatball is purely illustrative.
