Republicans anti-slavery?? Noooooo, surely you jest?
I'm pretty sure it was Democrats who fought for Big Government, Unions & equality and they were opposed by those nasty racist Lincoln Republicans, right?
Isn't that what they teach in school these days?
So when Lee was fighting Mexico, he didn't think he was fighting for his nation?
Lee's father was Federalist -- he didn't think the US was his country?
We can't get inside the heads of people back then, but it must have been more complicated than he says.
Madison and Monroe and Tyler and Polk must have had some sense that they were serving a united nation in the days before slavery became a major issue.
P.S. Lee wasn't an "opponent of slavery" in any real way. A letter to his wife saying that he hoped God would get rid of slavery when it had done its work isn't "opposition" to slavery.
Robert E. Lee would have felt like a traitor to Virginia if he had heeded the call from the United States to fight against his countrymen in Virginia.
And did he "feel" like a traitor for fighting against the country he'd sworn an oath of allegiance to?
If you want to be tolerant and sympathetic when it comes to Lee, fine, but you have to show the same tolerance and sympathy to other people and their difficult cases.
