The libertarian flag is yellow and black. The anarchist flag is black and red.
The implication is that a libertarian only looks like an anarchist by proximity. As soon as they're left to their own devices, they're revealed to be Christian Nationalists (the black symbol on white robes is used by the Klan.)
Most ancaps/right-libertarians are often just right-authoritarians that like drugs, addicted to loli-hentai (although this one is falling out of fashion due to "nofap" reasons), weirdly "free speech extremists", etc. Exceptions may apply.
I think labeling is so fucking stupid. Like I get that it’s easier to shove a label on people and yourself, but we’re seriously assigning an entire fucking socio-political economic identity to this kid from like 2 Goodreads reviews and a few Facebook posts?
Base on what I've read about this kid: I probably wouldn't like him as a person. I probably wouldn't agree with a lot of the things he believes, and I'd probably vehemently oppose a lot of it. I don't think he's a genius -- in fact I think he's probably a similar to the edgy, dumb kid I was at that age.
Sometimes "good" people do bad things, and sometimes "bad" people do good things: real people aren't one dimensional caricatures.
