If it differs in meaning I can understand that Similar to the Nazi s taking the Swastika from other cultures thus changing it s meaning However the Haitian for example could know the meaning behind what s on the sword altered it for purely aesthetics value and using it the same way We don t know enough about why the Haitian who I believe is the only one that has the symbol intentionally has the necklace to make the assumption that it s a different meaning Once we know why the Haitian has it then we can make those comparisons
