The children of Israel went out of Egypt ARMED.
And the phillisteins also made it illegal for Hebrews to work in IRON, so that by Samuels and King Sauls time no one had any swords or spears ( other than makeshift. It took King Saul ( Benjeminite) to re-organize the Hebrews allong millitary lines as they were under Moses, Jashua, Pinnias ( pinchas), Otniel, etc.
Purim is a hoiliday of SELF DEFENSE. ( Persian king "allowed" Israelites to defend themselves).
It's not jsut Natzi Germany, it's WORMS ( crusades), its Chelmitsky ( "cossacks"), programs, etc. etc.
I dont see why ANY religious, or thinking person ( Hebrew or not) would be against tools to defend.
We are commanded to look at ourselves as if WE personally were enslaved in Egypt, and were rescued. We are not permitted by G-dly decree to forget we are "Free Men". Slave mentality is stricly FORBIDDEN.
