The parts of the page that must be older from more credible editors clearly indicate a diadem is something specific that is unique from other types of metal headwear things but then people messed up the page to expand the meaning and to be racist fools who won t leave it be as an Eastern thing of any kind Literally the groups that must have been added in directly hype up the favorite ethnicities of white supremacists black supremacists and Middle Eastern supremacists And at least one of the examples used by white supremacists is not a diadem from what diadem seems to mean but a normal European crown so WTF
