How about the truth that most communities are built around some kind of nonsense, and maybe you can deal with a bit of nonsense to enjoy the benefits of community?
I can't think of a way to feel more hollow like the OP describes. Not making any claims or suggestions for others just pointing out how different that would make me feel compared to the suggestion. Different strokes for different folks apparently.
And if you do, you better have a new game plan for happiness and your friend group.
