Should AKB48's Minegishi Minami Be Demoted?

If you're not paying attention to the J-Pop world let me bring you up to speed. One of the first generation members of AKB48 Minegishi Minami has been demoted to trainee status, due to spending a night at her boyfriend's Alan Shirhama's house. One of the main rules of AKB48 is that you're not allow to date. Minegishi Minami age 20 broke the rule and was demoted, she later on went to shave her head and made a public apology to her fans. The video is now private on the AKB48 official Youtube channel so you won't get to see the apology. However I did find another channel that had a few seconds of the clip. Check it out below. 

Minami did break the rules but should she be demoted and kicked out? Personally I think the rules of no dating for AKB48 should not effect the stars that are 18 and up. AKB members that are below 18 I think that rule should apply to them. Minami is 20 years old and naturally love will eventually come across her path, she is a human and urges and feelings will take over. A 20 year old is at the stage where they really get serious exploring the dating world, this is a time they find out about themselves. It's an important stage in a young adult's life. However looking at it from the perspective of a manager or business. Minami did know the rules and broke them. It's like playing sports, if you miss a number of practice sessions the coach will bench you. There are rules we all must follow and if you break something that you agreed on, you have to be punished simple as that. I think the apology was going a little too far. A simple apology to her fans on a social network like Twitter would have been fine. I think the self punishment was a little overboard. Do I think Minami should be demoted? No! Do I think she should punished for breaking the rules she agreed too? Yes maybe like a miss performance or something like that. What do you think? Was Minami demotion too far? Was her apology too far?
