That’s the thing-—in American, and world, history you rarely see it coming. In 1855’ NO ONE, including Lincoln, would have predicted that 10 years later all slaves would be free. In 1774, NO ONE, including Adams, Jefferson, or Washington, would have thought that just 7 years later (really) America would be an independent nation.
When you said “you” I read it as you were implying that I personally was quick to change my beliefs when now, I realize that you were using the word “you” as the nation.
That’s why I responded to your post.
