I don't have time for a longer answer but I think you misunderstood me. My whole point is exactly that those religions do not focus on metaphysical beliefs.
They focus on ritual aspects, practice and social activities. It's exactly because they focus on the material aspects of worship that I don't think they matter much in terms of being a materialistic socialist. They don't impose metaphysical explanations for why society has a given structure or how to achieve such and such goal as a society.
They focus on activities and practices, both social and individual. They don't require that you adhere to specific metaphysical beliefs to engage in those practices.
For example: I don't believe in the actuality of metaphysical spirits and yet I find the practices of Umbanda tremendously meaningful for me as an individual journey of enlightenment and the social activities very fulfilling culturally.
About your last comment (imposing social behavior norms with threats of spiritual punishment) that's so incredibly Christianity centric. My religion has nothing of the sort, for example. Judaism doesn't even have a concept of hell. And although Islam have something similar for some branches, it's much less important than it is for Christianity.
What I mean by sociality is nothing of that sort. It's simply social activities. Festivals, collective worship, social gatherings, communal rituals, etc. Those things are tremendously more important for most religions than merely specific sets of metaphysical beliefs about the nature of things.
I used the API to overwrite and delete all my messages and deleted my account today.
I'm slowly deleting all my social media accounts and stay only on fediverse stuff. I think the slower, less FOMO driven nature of Lemmy will make it a more healthy to find people to talk with.
