I just never met such people irl so I have no idea what that is like. Like, having a bunch of people trying to gaslight you into believing in these stories feels like a nightmare to me, I can see why you would say you believe just to make the nightmare end.
The only very religious person I talked to about these things irl said that belief is a very personal thing and he didn't care about what others thinks or doesn't think. I think that is much healthier, and with such an approach you get almost no believers since there is no longer any pressure to believe things we wouldn't naturally believe in.
Anyway, they're not really "gaslight[ing] you into believing in these stories" any more than a climate change activist is doing that. They believe their stories are true and that it would have a positive effect on you and the world if you too were to believe in it.
Anyway, unlike fantasy stories, religious people are led into belief due to things like people insisting that a religion is true, arguments that suggest that God exist, and spiritual experiences. Maybe this isn't convincing to you, but it's markedly different from a fairy tale.
