I label it as fluffy because the set is fluffed with symbols solely altered or made up with meaning attached that represented or promoted far right Nationalism. Not that it cannot be used for magic, but the thing is "fluffed" up with nonsense. Fillers, additives, misrepresentation, misleading meanings, etc.
And I firmly believe that sigils, symbols, and systems created by someone contains an essence of its creator, especially something so relatively modern. Are you sure you want caught up in that?
I presume you're not a fully devoted, reconstructionist heathen, otherwise you'd be outraged that this "futhark" even exists. What with all the white supremacists, nationalists, fascists, and racists misappropriating and bastardizing our symbols and faith and all.
