These kids seem to have been indoctrinated into a cult of Curtis Yarvin. They love talking about Nietzschean and Yarvinist ideas like this one and cathedrals. This same creep had a quote on his Twitter bio that reads "there are cathedrals everywhere for those with eyes to see". If you don't get the reference, do some research on Yarvin. I think these people legitimately have dangerous intents.
I really hate reading Yarvin, who I feel is an extremist niche weirdo, but fellow geeks keep referring me to him. Got a tldr? What's wrong with seeing cathedrals everywhere?
None of us live in an ideal vacuum and this word has been tainted by its use in nazi ideology. Whomever wrote that has a responsibility to know what the words they use mean.
The combination of symbols is not random either. For example: taken individually, I'm willing to believe we're talking about Kantian Weltanschauung, Nietzschean Übermenschen, Nordic runes, medieval wolfsangel, Roman salute, or east-Asian swastika. But if I notice several at once, I will become quite suspicious.
