The point is that "love thine enemy" is COUNTER-INSTINCTIVE and leads to inevitable and logical PACIFISM.
Like GANDHI. PACIFISM seemed to work out pretty well in the struggle to overthrow the Brits.
Christians love to claim there are exceptions to "love thine enemy", but THEY AREN'T SCRIPTURAL.
Jesus never says, "love thine enemy, I mean, unless they're trying to hurt you in some way, then beat the Schmidt out of them..."
