@homelessjun@actuallyautistic@autism101@aproposnix@CynAq I always found that stupid, but never as much as when I learned that so many of the "rules" used for the "simple" symbolic transformations in mathematics are indeed completely arbitrary without the proofs.
In other words, they already taught us what they consider "cheating" but because /they/ did it it's fine. Such a double-standard is complete bullshit in my opinion.
