The Judaism of today is an exceedingly pale reflection of what it was in Tenach times, and what it will be again in Messianic times.
If you witnessed the ruthless no-prisoner slaughters of our enemies, as related in the Tenach, carried out by Moshe, Yehoshua, Gideon, Saul, David, Yehuda Hamaccabi, Bar Kochba etc all at the command of Hashem, of men women, children and animals, so contrary to the prevalent liberalist "live and let live" mindset, that you too would squeal "Oooh! You're soooo cruel! Attah Nazi!".
But you'd be wrong!
"Meir Kahane was a reincarnation of a Tenach warrior!" (R.Mordechai Eliyahu). That's why Kahane was so hated: he was a man out of time, from a different epoch. He was pure Tenach!
Chaim would also be ruthless with his foes. People can sense that. That he means what he says. That he cannot be bought. That he cannot be swayed. That he cannot be deterred. That he would implement his agenda, and swiftly too. That's why they call him "Nazi" too!
