Have you ever been legally detained by law enforcement in Texas and have been mistaken for a Hispanic? I've traveled to the mainland and I too have been mistaken for Hispanic in every state that I traveled to, but I have never once been detained by law enforcement.  If the situation arrives, I would have no problem of informing them that I am from a small island in the middle of the Pacific so they can then deport me back to the country I came from...America.
