Suppose that we just acknowledge from the get-go that any two given religions or subcultures will have many compatibilities and many incompatibilities. And suppose we do not whitewash that fact, ignore the differences, or try to craft language to obscure those disharmonies.
Suppose that we try to build a society that acknowledges that there will be inevitable conflicts between that society's respective subcultures. Where we teach people that the mere existence of conflict is not an existential threat.
What would the foundations of that society look like?
So you're a Christian. I'm gonna discuss a few points that make the rest of us uncomfortable around monotheism.
One, monotheism is against everything but itself, including the thing you can't change, the world. It separates itself from the nature of ourselves, inextricably tied to the natural, shared world, and anti-nature doesn't work. I'll give you an example. Current-day farming uses lots of synthetic pieces and parts. Those leak into food, water reservoirs, and the otherwise environment. Regenerative farming is farming without destruction to Nature's ecosystem, it mimics Nature. And it doesn't poison us. And makes great food. Whole foods food that doesn't kill you overtime.
The whole premise of subdue your nature to the point of impotence of fun is actually altogether damaging. Even down to prostate cancer if a male doesn't cum every once in a while.
Certainly, moderated pleasure ends up being better than wanton tomfoolery, but none of the religions preach this. They all made the mistake of seeing the destructive POTENTIAL and threw the baby out with the bath water.
If you don't have fun, you start to make it.
Onto the maybe, slightly, more important point...
You guys have a unified fantasy where all the nonbelievers die. You can see why everyone but your friends hates you. I wish I could say more, but it's impolite. Seriously, have wherewithal.
