Thanks for the discussion, but the wall was just an example. My question is about changing morality. Perhaps instead of Chuck's clips, I should have used the Pelosi quote, "... most of us, speaking for myself, consider the wall immoral, ineffective, expensive, and the president said he promised it. He also promised Mexico would pay for it. So, even if they did, it's immoral still ... ".
When did a wall become immoral? We've used walls forever, and still do. Instead of walls, I could have used abortion. 50 years ago it was generally considered immoral. Now the majority doesn't think so. 100 years ago racial discrimination was accepted. Now not so much. Please don't start a debate about any of these examples. I'm simply asking how morals change.
In my mind, morality transcends race, creed, color and politics. I don't care where you're from or who you are, some things are immoral. So how do those things change?
