But there was always this underlying, uncomfortable "threat" that an adult would approach you to talk about your relationship with god or whatever since that's the whole motive of the place existing.
If you're not into that, then you feel out of place. Like being a straight guy at a gay bar who's only there for the happy hour. Or hanging out at a cafe without wanting to buy anything.
We need to come up with something without any motive other than "here's a place to just be".
You were uncomfortable but not forced into traumatic situations. You probably absorbed some sense of morality in line with christian values as well. I imagine you did not sense a threat of someone walking up and offering you adderall or cigarettes. If one of my teens told me that same story I'd be a-ok with it.
My view is if there is no guiding principal the culture will devolve into base behaviors. Especially teenagers without a good capacity for future planning. And that religion is how humans get that job done, warts and all.
Looking at their website it's hard to tell. Their calendar doesn't show any activities like that, but maybe you have to be plugged into the congregation to know. They appear to be a very left-leaning Evangelical organization now. I didn't even know there was such a thing.
