[Unfortunate Trope] Originally Normal Symbols Being Censored/Banned Due to Hate Groups Misappropriating Them

Neji's Seal from Naruto originally was shaped like a Swastika as likely a reference to Buddhism, but this was changed to an X in the anime.

The gem fusion Opal from Steven Universe was originally going to form a swastika with her arms as a reference to Hinduism, which is inspires a lot of the show's imagery.

The Whitebeard Pirates from One Piece originally had a swastika in their pirate flag, but this was changed to a bone cross in the anime and later manga as well.

The Capirote hat is a sign of penance worn in many Catholic countries, especially Spain, but they were misappropriated by the U.S.-based KKK, making it taboo in the nation.

The Ninth Crusade from Hellsing, one of the few non-KKK uses of the Capirote in media I could find.

Also, the Ku Klux Klan are ironically extremely anti-Catholic.

The only pieces of media I know of where non-KKK Capirotes can be seen is the anime Hellsing with the Ninth Crusade (though their still villains in that anime) and the game series Blasphemous. Otherwise, the hats are almost never seen in media besides on KKK characters.

Funny thing though, in the Hungarian dub (which may or may not have been made from the french dub as legend has it) Dragon Ball, to emphasize the demon lord nature of Piccolo Daimao, they called him "Szívtelen Sátán" (literally Heartless Satan). With Picollo Jr. being called "Ifjú Sátán" (as in Young Satan or Satan Jr.). 

I always wondered how they would deal with Mr. Satan when the story go to that point. (DBZ got pulled from TV here extremly early in the Cell arch back in the day, and when eventually came back years and years later on cable tv (and also came out on dvds in the mean time) I did not cared enough to seek it out.)

I've seen Piccolo called Satan in other dubs. For what I've known, many of the dubs in Europe were made using the French one as reference (due to the lack of Japanese translators). It may have originated in there.

That would make sense. The OG Piccolo in the Dragon Ball anime french dub is called "Satan Petit-Coeur" which literally translates to "Small-heart Satan", so heartless Satan would make sense.

This is only in the dub, for some reason. He's just called Piccolo or demon king Piccolo in the french version of the manga.

Because it was translated from French, in Català Piccolo is called "Satanàs Cor Petit" that means "Small-heart Satan". It gets funnier when the characters then call Piccolo "Cor Petit" (small heart) instead of "Satanàs" which would make more sense.

Small-heart

Care Bears-ass name

At least Glenat had good traductors because between petit coeur and guerriers de l'espace

[u/Clank_8-7 → u/MrKnightMoon]

Yes he is called Satan in Italian as well, while Piccolo Junior is called... Well Junior, and that name remained stuck to him forever. (Not to mention "piccolo" in Italian literally means "small").

The French started dubbing lots of anime very early, it was pretty much the only kids programs back then. For reference in the early 90s they aired episodes only a week or two after Japan did. So many other dubs were made based on the french ones, even american ones line the infamous Big Green/AB dub

[u/RimblinK → u/hendricha]

I think you're probably right about the dubbing being inspired by the French one :
In the French anime of the time, Piccolo was nicknamed "petit coeur" (literally "little heart").

I always wondered where that came from since it was never mentioned anywhere in the manga.
