Do you remember a post number?
Here, I'll restate it.
FWIW, I think anyone who thinks Jesus was saying to not resist period in any situation like your family about to be brutally ravaged or something like that is deliberately attempting to avoid the context of the rest of the statement and would be implying Jesus was a complete idiot. I don't think ANYONE would have followed a teaching to not fight back in any situation whatsoever (except a few Darwin award candidates), and such a belief would have died out in a matter of months if that's how it was being interpreted.
The examples he uses are not life threatening situations. Being forced to walk a mile by a Roman Centurion, being slapped in the face, being sued, etc. All those have one thing in common: NOT LETHAL. Or even that dangerous.
The word "resist" in question here is not about Violent resistance. It's about opposing, but not like the English-language idea of "violent resistance".
Strong's Greek: 436. ????????? (anthistémi) -- to set against, i.e. withstand
I challenge you to find one use of Anthistemi where it applies to actual physical resistance in the face of danger.
This is the gotquestions.org article (A site I normally hate but is still a broken clock right twice a day) I used to support this notion.
What does the Bible say about self-defense?
Here's another:
What Did Jesus Mean When He Said to Turn the Other Cheek (Matthew 5:39)?* | Answers To Tough Questions
Does this mean that we should never resist when somebody attacks us? Should we let everyone take advantage of us?
This can’t be what Jesus meant. After all, Jesus denounced the Pharisees who attacked Him ( Matthew 23 ), and objected when He was struck by one of the officers of the high priest ( John 18:22-23). Further, He advised His disciples to take measures to defend themselves ( Matthew 10:16; Luke 22:36-38 ). He also declared that they shouldn’t worry beforehand about how they should respond to their enemies’ charges, because He would give them the right words to say so that their adversaries wouldn’t be able “to contradict or resist” them ( Luke 21:14-15 ).
Similarly, the apostle Paul aggressively defended himself against his enemies, asserting his rights as a Roman citizen, and making it clear to his attackers that there could be consequences if he were unlawfully harmed ( Acts 23:1-3; 25:14-27 ).
So I think it's quite clear that Jesus was not referring to total non-resistance in all situations, and that the word "resist" and the examples he gave were not about serious situations where life, limb, and physical sanctity were at stake.
