There is a classic rule exists called love-prohibition policy.
They signed contracts which this rule is included
They’re aware, they agreed and they signed it consciously.
As AKB member, no matter what a contract must be respected and obeyed. (just like in other working environments, rules must be obeyed or you’re fired)
To have love, sure is everyone’s rights, but not as long as she’s still in AKB. Please see the difference.
If they want to have love or don’t agree anymore with the love-prohibition policy, they can quit. No compulsion.
There’s NO human rights violation in AKB48. They’re allowed to live their life just like us, just NO requited love/sex. (And you won’t die for not having boyfriend and having sex right, idiots?)
Also, they’re not allowed to smoke.
There’s no such thing called slavery in AKB48. They’re paid based on their works, they have rights to choose or leave some jobs if they don’t want to do it, they got holidays and they got luxury facilities.
There is NO silly punishment such as shaving head. Minegishi Minami did it on her will to show fans she’s responsible and feeling so guilty about breaking the rule. It shows dedication. And yes, it’s silly and too extreme. Well, everyone can do stupid thing if she/he’s panic or stressed.
Minegishi herself chose (no force) to stay in AKB while she has rights to leave this group for love. It means her job as an idol is more important than having a boyfriend.
Minegishi Minami’s punishment from management is only demoting her to what AKB called “kenkyusei” (trainee)
