Describe how the Nazis used the Swastika to persecute others.

What an oversimplification!!!

" .... and to identify people who were to be arrested or sent to concentration camps"
That is just plain false.
(the main Naxi personelle like Himmler all wore the swastika on their arms
does that mean they were labelled for arrest ????)

The Nazis used the swastika as a symbol of their power and to persecute those who did not conform to their ideology. The swastika was used to identify Jews, political opponents, and other groups deemed undesirable by the Nazis. It was used to mark homes, businesses, and other public places, and to identify people who were to be arrested or sent to concentration camps. The swastika was also used to intimidate and humiliate those who were persecuted by the Nazis. It was a powerful symbol of Nazi power and a reminder of the horrors of the Holocaust.
