#1) I really don't appreciate the proselytizing tone of your posts, Mahatma Gandhi. This is a Jewish forum. This is a warning.
#2) I remember the J-man beating up people selling stuff in the temple. That doesn't sound very peaceful to me and these people weren't even threatening his life or the life of any others.
In the temple he found those who were selling oxen and sheep and pigeons, and the moneychangers at their business. And making a whip of cords, he drove them all, with the sheep and oxen, out of the temple; and he poured out the coins of the money-changers, and overturned their tables. And he told those who sold the pigeons, "Take these things away; you shall not make my Father's house a house of trade." John 2:14-16
The J-man did not say turn the other cheek if your life was in danger. You have taken that WAY too far in a way which was never intended. That was intended for petty insults or arguments. Again, this is not a compatible ideology with Judaism. G-d told Israel to wipe out entire nations.
#3) Letting your enemy kill you and your family is not only unsound and immoral, it goes against what the Bible teaches. You don't know your Bible very well.
"Do not circulate gossip or stand by idly when your brother's life is endangered." Leviticus 19:16
"And David said unto his men, Gird ye on every man his sword. And they girded on every man his sword; and David also girded on his sword: and there went up after David about four hundred men; and two hundred abode by the stuff." 1 Samuel 25:13
"Blessed be the LORD my strength which teacheth my hands to war, and my fingers to fight," Psalms 144:1.
And one just for you since I am not a Christian: "Then said he unto them, But now, he that hath a purse, let him take it, and likewise his scrip: and he that hath no sword, let him sell his garment, and buy one." Luke 22:36
