Star-imitators

As you saw, my post is about star-imitators. Why do people imitate them? I mean, it's okay if they idolize them, lots of people are like that, but still, they shouldn't imitate EVERYTHING they do. It gets irritating when people start acting plastic, because it's not them, it's another person. Everyone is different, so why even bother imitating other people? I've had encounters with star-imitators, and in my opinion, they are like barbie dolls. I mean, they are plastic and prissy. I don't hate them, that is another story, but still, it gets annoying. I guess it's inevitable, there will ALWAYS be people like that, but can't they keep the annoyance to a minimum!?
