Good observation, BykrBayb. C.S. Lewis had their number. Perelandra, the second work in his space trilogy, is all about the temptation of Eve -- i.e., all temptation by evil. It employs virtually every argument that evil can muster.
If I may put it simply, in God's good creation, there is no pure evil; only a warping or bending of the good. Leftists do that by seizing on some tiny good at the expense of greater good. They fixate on a tree and intentionally ignore the forest. Their thinking is all about procedure but they shut their eyes to principle. Their moral point may be correct at a micro level, and that may satisfy the simple-minded, but you have to see if the moral law is affronted in a larger sense.
Thereby the right-to-die gang can stand up close and dither about due process. The world stands back a few feet and sees America torture an innocent woman to death.
You know how I adore politicians and other odious world savers. I remember smiling at a quote from an astronaut on the moon, back when:
"From out there on the moon, international politics look so petty. You want to grab a politician by the scruff of the neck and drag him a quarter of a million miles out and say, 'Look at that, you son of a bitch.'" --Edgar Mitchell.
Right-to-die activists should be dragged to the bedside of the woman they are killing and and told to "Look at that, you son of a bitch."
The most potent lies may be those cloaked in and wrapped around a powerful truth. The closer to Truth a lie may be, the greater its power to deceive.
