From the great article that is linked to this one.

" Hope, her mother and three of her siblings sailed with 106 other Aleuts from Unalaska. The settlement was the only one with a substantial white population, and those residents -- including Hope's father, the postmaster -- were not a part of the evacuation. Hope remembered seeing him standing on the beach in front of their house, "waving frantically" as his family receded towards the horizon. Over the coming weeks and months, Hope told me, her father would seek answers about his wife and children. "Trying and trying, calling everybody, writing to Washington, D.C., trying to find out. Nobody would tell anybody what the plan was. It was like being part of a huge secret."

More research available.
I have spoken, over the years, to Aleuts who were sent here, who remained or returned, after the war. My son-in law's grandmother being one. 
The accounts are true, whites were treated differently. 
Lots of reasons why, not all racism.
