Why can't youths of Indian heritage be themselves?

I'm Indian, so are my parents who are from the Carribean. However I have noticed that a lot of American-born youths of Indo-Carribean (West Indian) or East Indian heritage tend to try to emulate those around them to the point that its so obvious. Although there is nothing wrong with wanting to fit in or admiring a culture or scene that inspires you. However one should appreciate their heritage although they are born here. Although being an American is part of who you are as well.
