So, multiculturalism is a problem I have run into for my shit-posting-almost-rip-off-of-the-SCP-department-mixed-with-SWAT-fan-girling X-files thingy, TSADF. You see, if you have a world where monsters are real, especially monsters of the cultural veraity, you run into a problem. A serious one. How does shit over-lap and interact with one another. Like, if you have a vampire, that wants to enter a Hindu temple, would it count as holy ground in the same manner a chruch would? Cause you could argue, that holy ground is universal, but vampires aren't serving in the same religion as Hindu's which would more or less mean a clash between the monotheistic ideals of Chrisitanity and the polotheistic ideals of Hinduism. Which means Christianity must therefore be false or almost false, which than causing another problem, why vampires even get effected by holy ground ideals in the first place if the mythology around them being effected by holy ground is Christian?
Do you see what I'm saying, reader? Am I fucking insane?! Yes, but in this instence? Am I?. Also, what about people of two seperate heritages, can you have someone who is a werewolf if their only half part of the cultures that have werewolves. Like if you have someone who is half Irish, and half wolfwalker as a side effect, would it be like other inherited traits and be a coin toss on if you have it? Or would the woldwaker traits be much weaker. 'Cause like, I'm half God half Giant, and I have more godly traits and some giant traits, but you'd have a hard time telling which triats are where due to how watered down both are. Would it be like that? And what about the moral issues that would arise?
Like, if magic is real, some cultures would have more justification in messed up traditions. Such as the Vikings having been justified in Bloody Eagling someone as it really was pleasing to an actual real god. In other words if there were an actual scientifically proven god that wants you to die for it, what would the moral implications of sociaty be? Like, modern day humans, with science, can argue against what we call immoral acts, but if the fucking actual sun god wants human hearts to keep living and giving us sun light, wouldn't that make it morally upstanding to continue the sacrifices?
Furthermore, how would curses carry over? Like if a vampire bite someone who was Native America, would the person have to go to a Native American Shamen or a Christian Priest to figure out a cure? As on one hand, the Native American gods would also technically be real or at the very least the magic related to them is, but vice versa for Christian shit. And the vampire is a now Christian mythological creature (was originally Welsh but no one really likes the Welsh or remembers them so... Also, it got Christianised) so how does our poor Native American friend figure out the cure?
Narratively, I feel like it would be best if each cultures monsters, curses, magics and so on belongs to them and thus requires them to solve it. So, a Wendigo can't just be shot with silver bullets by a Christian priest, but well, that also means a Native American Shamen can't do jack shit 'bout a vampire. I think for story telling it works best, than you can have a full crew of folks who specialise on certain mythologies and can focus on defeating that type of monster as well as preventing the solution from just being holy water and silver bullets.
