Even if you ignore the dreadlocks aspect, I've seen people go far beyond that and claim all kinds of very obviously African hairstyles and be like "no actually the vikings...".
Like, I find it weird that somehow the vikings invented literally every single African hairstyle in existence, even the ones that make literally no sense for a white person to even have, since most of these styles exist in the very specific way that they do to protect whatever type of African hair is most common in the region where that style is from.
Why in the world would medieval vikings invent insanely time consuming and impractical protective hairstyles (that do more damage to their hair than anything else) for their allegedly long flowing straight hair that takes extra effort to even make this kind of hairstyle stay in place for them???
And given just how many hairstyles I've seen claimed under the banner of "vikings", it's super wild that somehow the vikings invented a whole lot of very specific shit apparently in parallel with every African nation and tribe under the sun, except one has incredibly well-documented and researched explanations for every single individual hairstyle existing, and the other has airbrushed art on the side of a dude's van to document that the vikings did indeed do all of this.
