As a German with history major course in high school and pretty much 5 years of school time with pre 1945 Germany/Europe curriculum I am of the opinion that they could have not.
The systematic deportation of dissidents wasn't announced overnight.
And the disliking of Jews was almost the same in whole Europe.
Pre-1933 there have already been officials in place that started to limit the supply of weapons especially to Jews.
With Hitler's official reign 1933, the German state conducted raids mainly focused on Berlin, famous people like Einstein and in a few other large cities.
Unannounced, systematic, intel-based search and seizures throughout all the years of the third reich. We are talking years. Until 1938 and further.
The idea of jews taking a K98 into their hands to protect their family? This alone means having no clue how the mind set was back then. And your enemy wasn't knocking on your door announcing himself.
Imagine you and your family are swatted in the night by multiple SS-officers and Gestapo. How would weapons come in handy here?
I can only imagine the lynching when suddenly Jews were reported shooting military or "police" officially "investigating"
Furthermore the Nazis implemented a system of ghettoization - which was pretty much welcomed by the Jew-hating population and happened over years.
Jews had the third reich military AND the hostility of the civilian population working against them.
You either had enough money to flee beforehand or you tried to hide and hope for the best.
Yes, there have been ghetto uprisings, but most revolt came from the underground.
There had also been resistance, even throughout the German non-Jew population. But whilst even high-ranking traitors failed to assassinate Hitler, you had the common mass celebrating the death of millions.
Saying privately owned guns were a way to prevent the
final solution
is not only completely ignorant, it is outright disrespectful to history, the amount of work and study done on this horrible highlight of the wrongdoings of humankind as well as the 60 million casualties.
