What made me think about it is, not too long ago the James Bond movies were getting a lot of flack for their misogynistic treatment of women and the outrage spilled over into their portrayal of non-white races. The Voodoo Witch Doctor in Live and Let Die was often mentioned. Considering the first thing that came to mind while watching PatF and Dr. Facilier hit the screen was the Witch Doctor from Live and Let Die, I can easily see how Dr. Facilier could also come under SJW fire.
I'm going to say the voodoo witch doctor should not be a problem as it is heavily rooted in Afro Creole and Afro Islander culture and history. Even to this day, voodoo doctors operate in New Orleans.
