You forgot the incest, shitstain! It's the most important part! Sex is only good if it's your sister kind of!
Hym "Yeah it's like a cannibal suffering cult that is, like, super stoked about how they murdered an innocent guy without remorse... But it ALSO... Has INCEST! It's the most important part! The incest IS the religion! The whole goal of the religious is to perform that sweet, sweet incest ritual! And it's super important to them that people are forced to do it! They really want you to make a chick your sister (technically) and then fuck a baby into your kind-of sister. They're also the gimps for the Jews! And the jews are functionally equivalent to a Jesus. That's a thing too."

basically when people who were raised as siblings and/or family start a romantic relationship. Ex: Any of the "Kissing Booth" movies.
The relationship between those kids is basically moral incest, they were raised like siblings! Gross..
