I don't know that it is a religion, so much as a stage between religions, where the old order has broken and the new has yet to emerge from the swirl of chaos.
Sex is a binary. People are a spectrum. Those who produce the next generation are necessarily the core, while much of the rest is fringe. some otherwise healthy, some not so healthy, but all necessary, as nature is trial and error.
When they try to turn it inside out and make fringe the core and core the fringe, it is destabilizing and eventful, but necessarily not permenant.
Some are seed. The rest is fertilizer.
Life has been trying every possible angle for billions of years.
Without the ups and downs, it would be a flatline.
