I'm not rationalizing anything. I'm merely pointing out legal reality. Immigration law is not criminal law, the procedures aren't criminal, the standard of proof isn't criminal. You may not like it, you may not agree with it, but that is reality. Substituting your own opinions for reality is not a healthy or particularly effective way to go through life.
Populists, like Trump, attract losers. It's clear because he talks about winning and being successful so much (people who are already winning and being successful don't need to be told what it looks like. they already know.) And the reason why Trump supporters are by and large losers is that society has changed over the past 50 years away from simple tasks to complicated systems that cannot be easily reduced to a simple slogan or two. They are systems that operate based on the laws of the universe, which aren't subject to our own individual opinions and beliefs. Attempting to navigate through such a world with solution making skills more appropriate to being the assistant manager at an Interstate gas bar... no wonder the coastal elites have made out like bandits.
When I first started in my career, I was amazed that I could make six figures simply by being able to string three or four complicated systems together and predict the changes in system 4 based on the inputs in system 1. To most of the people I worked with, what I was doing was akin to magic. In these 50 years we've forced people to deal with complicated systems with effects over many years. Most people can barely balance monthly expenditures in a check book, yet now they are on the hook for saving for a retirement 40 years ago (and it's not surprising people are abysmal at it).
But no matter what, you cannot succeed by reducing things to a simple slogan or rejecting the world in favor of what you feel it should be. Saying we should "build a wall" or "light up a few truckloads" to fix illegal immigration is no different than breaking your computer when it has an error message - it may be personally satisfying, but not effective. And this is why populists, like their supporters, rarely succeed. Their slogans are an emotional sugar high but their solutions don't actually work. They can temporarily blame others for their failing (Trump's greatest Cabinet ever is now a bunch of idiots it seems) but ultimately they will fail and be deserted.
