>>15080466no i'm saying that in japan enforcing a strict black hair rule was functunally the same as a ban on dyed hair since when the law was made like 99+% of students were japanese and 99% of japanese have black hair. so any hair other than black would mean it was dyed to stand out. they didn't pick black arbitrarily as the color to enforce. and it worked well enough for what they were trying to do until fairly recently
well clearly they agree with you since they reppealed it. but there was a period in which it was enforced and i think it was simply because the law was outdated for a while and nobody bothered to reppeal it.
