You see the tyranny in FDR's imprisonment of the Japanese Americans, but fail to see that Lincoln's actions were much worse. One could conclude you think the rights of Japanese Americans are much more important than Southerns. ...
That makes absolutely no sense. Japanese Americans were not trying to destroy the country. They had not taken up arms against the country, and certainly weren't enslaving other people within the country. You are posting out of ill-considered emotion.
It makes a great deal of sense. FDR's actions were unconstitutional and tyrannical, just as was Lincoln's. FDR's tyranny may have been less murderous than Lincoln's, but it was still tyranny. Had the Japanese Americans resisted, they would most certainly have been murdered just as the Southerns were.
FDR believed the Japanese Americans were traitors so he imprisoned them. Lincoln saw Southerns the same way. Had the Japanese Americans been as numerous as the Southerns, they would have fought to prevent their imprisonment, as did the Southerns.
Lincoln invaded the South to keep it in the Union. That is clear to anyone who can think. So, he destroyed what he wanted to keep...and he did so purely for statist reasons...nothing to do with slavery.
