I think if people are a fan of a celeb, they tend to want to see the good side of him/her. I am neutral to the stars because at the end of the day, they are human and human are born with flaws. Perfection should never be required from anybody.
Remember Mint's mom did not fault Mark for whatever happened so far, she is directing it to his manager. This did not happened over night but through the years. I can only imagine a mother holding in things for so long when it comes to her kid. I mean, how long can you ignore and turn a blind eye on a situation that is hurting your kid? There is rumor going on for a while that Mark's manager doesn't like Mint so to many when things like this happened no one close to them or their devoted fans is surprise. What Mint's mom is disappointed with is the words Mark used toward her. It is very disrespectful regardless if you are a fan of his or not.
Mark might be growing up but he is quite naïve because to have a person altered the way you treat others is simply a child still. I don't mind if he listened to his manager but only if the manger truly has his best interest in heart, but when you start to see the chips fall down in a way that is hurting people then at a certain point you have to start questioning the other person's motive. And Mark isn't there yet.
An American celeb once said, when you decided to become a celebrity you trade your life for it. And many times over I think a lot of stars forget that. I applaud those that can separate a celebrity personal life from the actor itself. I guess, I am in the minority because I can't seem to overlook their actions off screen and on screen. Though, like I say no one is perfect but to make mistakes over and over again isn't going to win me over. It's sad to say, these stars are a reflection of themselves whether they are acting or not because they almost become one since their personal lives are also sometimes being played out like a movie/drama they are in. And as a fan, whether you want to get tangled up in it or not, I think it's almost a choice you don't have. Because we want to know about the stars so badly that it all becomes one.
As far as Mark staying quiet on this, it's almost his only choice. The only thing to me he could possibly say, is to apologize to Mint's mom. And I hope there are people around him still care enough about him to pull him aside and give wise advises. There has got to be someone other than his manager whispering stupid things in his ears. Those that truly love him would at least till him that words can cause as much heartache as one's action. Eventually, Mark will grow up but to me his steps might just be baby ones.
