Can you think of a better way to incorporate the atrocities in question with the teaching "don't deny those who ask of you?" I do understand your point, there are rape victims on here, and you know what I would think offends them the most? christians saying they shouldn't defend themselves, nor should other christians defend them. That would offend me and DOES offend me more than I could ever describe.
Anyone who stands by and knowingly lets evil happen obviously does not know God or his commands very well. We are NOT to be by-standers--we are to intervene and help, if we can. Jesus said "whatsoever you do to another, you do to me." The same applies if we DON'T do something for or to another person. How many of you would stand by and let Jesus get raped, simply because you dont want to defend him?
