Why is there a social stigma on shy or introverted people?

[MahaliaMAY]

I am quiet sometimes very. I am not shy though i'm always labelled shy - sometimes it's as simple as not feeling like talking. We all have stigma..even the loud, out there personalities are thought to be outgoing and confident..more often than not, they're just the opposite. People see what they see and label it in their brains to make sense of it..it needs to be filed somewhere. It sits there until proven wrong. The more the label is proven correct, the more solidified it becomes. In addition to media influences really putting the nail in the coffin..voila we have stigma..LOL if that made sense....don't work yourself up over it, who cares..
