I've been told Native Americans often have problem with the "real names" policy because they often sound "fake" to people used to European names.

Yes. For example, Begay is a common Navajo surname. Others use traditional names (such as Standing Bear, for example). Odds are the people at facebook making these decisions have never known anyone with such a name.
