Nazis mistreated GI's who looked like Jews or sounded like Jews

An AOL news article says,

Berga an der Elster was a slave labor camp where 350 U.S. soldiers were beaten, starved, and forced to work in tunnels for the German government. The soldiers were singled out for "looking like Jews" or "sounding like Jews," or dubbed as undesirables, according to survivors. More than 100 soldiers perished at the camp or on a forced death march.

Even Americans can't identify Americans who "sound" like Jews -- how could the Germans?

Anyway, this story is consistent with what I have been saying for a long time: A "systematic" Jewish holocaust was impossible because the Nazis had no objective and reliable ways of identifying Jews and non-Jews.
