You say erroneously, I say dog whistle. Slaves were repatriated there. It’s a troll, and not the first time they’ve done this, see CPAC nazi symbol in 2021
I mean, this isn't an uncommon graphic design mistake, there's a whole subreddit for it. In this case it's far more likely to be a dumb mistake than an intentional dogwhistle like that suspiciously Odal rune shaped stage at CPAC may have been.
See, to me, that is far less crafty and far more stupid. If this was an attempt to troll with a slavery dog whistle, that's far more subtle and they aren't subtle.
Not that I know of. The Odal rune is obscure enough to the average person that they have plausible deniability, so unless we find design documents or get a confession it's basically impossible to prove.
