Jews are not caucasians...they are semites (which refers to
speakers of a language group that includes the Arabs).
Jews were distinguished from the other Europeans through the
language they speak, their religious practice (Judaism), their
names.
Got the following from the net:
"The identification, or singling out, the entire process was
gradual, not done in just one swoop. There were a number of
progressive steps over years. There wasn't just an announcement
"all Jews report to the station and prepare for
extermination".
For example, somewhat under the guise of needing to protect them,
(possibly from the hysteria and social unrest aimed at them by the
carefully crafted blaming of the Jews for all the problems, in
Germany and the world), Jews were required to self identify for a
while...and being law abiding citizens, they did. Later, these
identifactions were used to round them up.
Many lived in their own communities, and were identified that
way.
Identifying one, identified the family - not just by custom, but
because the family wouldn't abandon one of it's own.
Associating with Jews was considered just as bad as being one...so
if you were known to have been a friend, business acquantice, etc
of one, especially if you yourself weren't aryian looking and a
known Nazi supporter, was grounds to be considered one too.
Certainly many mis-identifications were made, based on predjuces,
like having a large nose, or such.
They were required at one time to move into and only live in
certain areas - or ghettos. Anyone in there was able to be presumed
to be a Jew. Not allowed to work, etc.
Remember, they were, and are, (perhaps fearful) but proud of being
Jewish.
Neighbors turned them in...and were rewarded for doing so.
Frequently given much of the families belongings. (Yes, again there
were many instances of someone lieing to get revenge on
another).
That even progressed to NOT reporting one you suspected as being
punishable as treason...and you and your family could be taken away
or killed as a "jew sympathizer".
Jewish men, then and now, were circumsized. The Nazi official could
require anyone, anywhere, to drop their pants and prove they
weren't Jewish.
Many Jews followed certain customs, laws and rituals that would
expose them or could be used to do so- if they keep Kosher for
example - forcing them to eat pork was vile and offensive, even
phyiscally impossible for someone brought up to avoid it. Wearing a
yamulkhe or prayer shawl was a dead giveaway.
Having any "Jewish things" in your house, prayer books, picture of
"obviously Jewish" relatives, all were enough proof. (And consider
Jews are required to have a mezzuah with a certain prayer on the
doorposts of their house). "
