Anime avatars are often a coin toss between (potential) comrade and chud, so it may be fun and maybe helpful to think about and share those in the place of that old 
bellwether for chuddery.
Mine is anyone with ".eth" as a suffix in their online name. I have yet to see a single person that does that that isn't a chud. 
It may even be cheating, but seeing an actual cryptofascist cartoon "original NFT do not steal" is a pretty reliable red flag too. 
EDIT: Oh yeah, I almost forgot. 
It's incredibly funny to me that the Art of War does contain some very useful insights, especially for the time, but everyone seems to be hell bent on repeating the most basic bitch conclusions from that text like they're an ancient chinese secret.
The importance of logistics, flexibility, mobility, and so forth are things organizations and militaries fuck up to this day but all anyone wants to talk about is how winning without fighting is the best. Wow, getting what I want without being punched in the face is better than getting what I want but also being punched in the face? Ground breaking.
