Actually your wrong....wow isn't that a shocker.Remember when America was in WW2 fighting Germany and Japan, and White America gathered up Japanese Asians and locked them up, yet they did nothing with the white Germans??
White America is soo racist.
According to the Time-Life series on WW2, the volume titled "The Home Front: U.S.A,":
"After war was declared, about 5,000 German-Americans were rounded up & interned at Ellis Island. By the end of 1942 most were released."
Those most likely to be arrested and relocated were those who were not well integrated. They could be interned on the basis of gossip and hearsay and things that no ordinary US court would take seriously. Usually, only adult men were interned, but in some cases their families obtained permission to join them.
