at what scale? medievalist shit is sports for nerds, modern small arms could have several motivations, and strategic layer armchair general stuff appeals to people who like geopolitics more than memorizing chess openings.
80 is still a "cheap because it'll break" price, you probably need at least $200 into an office chair to last a few years, but obviously don't pay any lifestyle scam shit like the gamer tax.
i think it's contextual. there are many situations we would do well to remember that our social-level actions impact the world we live in and we are impacted by it in turn.
one specific example of the demarcation being important is telling creationists to shut the fuck up. if you walk around in the woods and find something plainly artificial you've done so by contrast to the natural surroundings.
i draw the bare minimum line at being anticapitalist and broadly antinationalist (exception for liberatory/decolonial nationalism, and pragmatically not destroying your state while the US exists). a couple centuries ago i might have drawn the line at republicanism vs monarchism, and a couple centuries in the future if the capitalists are gone there'll probably be some struggles about how centrally organized the bureaucracy should be.
libs and so on obviously don't use my definition because it would correctly position them as right-wing.
i'm handwaving all social issues here obviously. A place like Burkina Faso needs the chance to follow Cuba's footsteps on queer rights and so on. In the future people may look back aghast on the AES of the 20th and 21st centuries for their carnism but i can't stand up and honestly say that i think veganism is inherent to leftism when it's not inherent to AES, not even Kerala.
What's the point of discovering new rules if you're not gonna see how they taste?
