tl;dw: he's an Australian sword youtuber who practices historical European martial arts (HEMA) and is much criticised by the HEMA community, he's an anti-woke nutjob with a fragile sense of masculinity, he's a gun nut who thinks Australia should have an equivalent to the 2nd amendment (which he's ranted and screamed about at length, showcasing why it's necessary to keep guns away from him), he's an "AI activist" who thinks writing words into a text box makes him an artist (while producing images that, even among his peers, look horrid), and he's the envious brother of the actual, successful artist Jazza (who seems like a genuinely fine dude). He also wrote the novel Shadow of the Conqueror, which is a boring, badly written, preachy self-insert power fantasy, where he moralizes that rape and the resulting pregnancy is good actually because motherhood is wonderful (I'm not paraphrasing that much, and it's still fucking disgusting to think about).
