NFT means non-fungible tokens.
Basically bitcoin, except not currency.
You can think of it like a collectible coin that's worth a lot, but isn't actually usable as money.
Since these are just arbitrary lines of code, it's hard getting people exicted for them.
That's why they're tied to art. The token represents ownership of a piece of digital art.
But, when promoting the art so people try to get the NFT, you have to show off the art, meaning it's publically accessable and you're wasting electricity trying to buy... Nothing.
I think the current interpretation of sectarianism privlages debates about dumb shit over debates over theory and actual politics. Anything significant enough to define a tendency receives extreme protection (except Trotskyism, which remains a punching bag), but you can be as divisive as you like over petty bullshit.
The sectarianism rule was supposed to promote unity, but it just redirects the division, failing to achievt its goal while restricting users and preventing what could be productive discussion.
