Honestly, that's an incredibly spacious way of viewing physical Christianity. What I mean is, the brush you paint with is very broad and although the devil is in the details, I prefer day to day, situation by situation determinations when it comes to that specific biblical scripture. Do unto others as you would have them do unto you? Look, she would have had me screw her, then walk out of her life forever. Why? Because that's her do unto others concept as she would have others do unto her. I won't say that would be wrong of her, I will say it would be wrong for me. We're all different and there are limits to our recompence or recompence expectation. I could suggest that those who aim to harm me, would want me to harm them in return. some maybe, but not all, so as I suggested, a discerning mind is required and every situation different than every other. We are required to utilize our truth when dealing with other people's truth, which is rarely known or understood. Even in kindness it can get tricky. I won't suggest that I wouldn't extend kindness or help others in a time of need, but this is largely dependent upon my ability. For example: The couple were having a domestic dispute. It isn't uncommon for them. She appeared to need help, but after coming to her aid, she turned against the one who stepped up and rendered him. Our pearls are important and very valuable, and we've also been taught not to cast them before swine. I may step up like that for those I love if needed, but don't expect my dog (pearl) to come to someone else's aid when it would certainly jeopardize my life and theirs. This happens enough for those we love to be so careless to do this for those we barely know.
