I can not believe what I just read. Are you; in fact, comparing the Two as being somehow equal in their actions? If not, I'll apologize now for what follows.
It was a different time, a different era. That aside, there is no comparison of the Two, not even within a shade.
FDR deported 'Illegal immigrants' because he knew they would work for a fraction of the wages of the American worker which didn't benefit his endeavor of the American Dream, as we knew it. Allowing illegal immigration today has the same effect but to the benefit of those who 'employ' them. Something I see Trump taking the slow train on.
FDR Segregating the Japanese to camps was Two fold. One, that we were at war with Japan and didn't know who the enemy was. Two, It kept the arse holes in our country from harassing, injuring, killing those citizens by taking the law in their own hands. Trump has condoned such actions against all those; who are in any way seen, as 'different'.
FDR's supposed packing of the court in favor of his policies is no different than any other Presidential nomination by either party.
The major difference between FDR and Trump; or any republican, is that FDR was for the people, which is what this government is supposed to stand for. Trump; on the other hand, has shown his only concern is for those in the top One percent. He will not lift us up. He will serve; as those before him, those that control him. He will regress this countries people at a much faster pace than Reagan, the Bushes and Bill Clinton; or for that matter Hillary, could never imagine.
There are no true similarities between them. To even infer the possibility indicates a need to retake American History.
