In neither scale not morality nor basic common sense is an invasion by Nazis comparable to immagrants seeking to enter the country. Whether you're on the side that sees them as refugees or economic migrants seeking a better life, they're neither invadors nor fascists seeking to rule the land they're trying to enter.
The people who are comparable, though, are the monsters who sit comfortably at home while cheering on a moron who would separate infants from their parents. And that's you. If you want a wall, build it around you and your ilk, and stay inside. I'm sure a Kickstarter for that will quickly surpass the 5.7 billion requested. And good riddance to the exceedingly stinky rubbish.
