Not one of my friends of British friends of carribbean descent are into voodoo. About half are church attending Christians (many of whom don’t even celebrate Halloween) and the rest are Muslim, agnostic or nominally Christian and a couple are atheist.
I do however know plenty of white British women into things like Ouija boards and crystals and Wicca.
Blaming it on voodoo in this scenario is bizarre and unnecessary and offensive. Unless there was some evidence or testimony from a friend or family to suggest this.
Why are you so determined to link it to voodoo as if poor mental health doesn’t affect people badly and MH on its own can’t be enough? What planet are you on- some people suffering with MH even kill their own children.
And there’s plenty of mentally ill people who unfortunately choose a method of death that is similar to their parents. It’s not unusual for example for a boy whose dad died by hanging to grow up and do choose that same method of death.
