I'm not going to argue that you have no right to say something like this, and while I appreciate having outside input, my point still stands. I never said it was only my folklore either. Don't get it twisted.
As much as I would like to agree with sharing culture, there is a time and a place. This is not one of those times, nor is it one of those places. If your whole argument is only questions, I'm going to disregard it. Wanting to protect my own folklore is not being elitist. It also doesn't matter if something is "derogatory" if it is appropriating culture. It's still bad.
Even if something is scary, that doesn't make it okay. That doesn't mean using someone else's culture is okay.
The fact you brought up another widely appropriated culture goes to show how little you understand about this topic.
There is no defending this.
