I don't disagree with you; I want to see the rot within the system completely and utterly excised. I personally don't believe that can happen through reconciliation but will take some hard lessons being learned. American history does not show that we will do anything other than "forgive and forget" however, and right now I see no signs that will change. My hope otherwise is in the youth of the party. We shall see.
Regarding your first point - this all has happened before. Many, many lawful Hispanic residents - including no small number of citizens - were driven out of the US in the 1930s (the "Mexican Repatriation"); estimates are anywhere between 200,000 and 3 million people. Loss of birthright citizenship? Oh yeah, we've done that too. My great-grandmother, born in Illinois to American citizens and who probably never left the country in her life, lost her US citizenship because she married a foreign national who had not (yet) naturalized. Yep, that was the law in the 1920s if you were a woman. She had to go through the naturalization process later, same as any alien; I have her naturalization papers. What is happening today feels different to us because in our lifetimes nothing like this has ever happened, but in the long, often ugly and usually xenophobic history of the USA we've always managed to be complete and total shitbags to some part of the population (and no, we're certainly not alone there, then or now).
Stephen Miller and his ilk - why, they can eat a giant bag of muledicks. I hear the mini-mart down at the Esso station might have some, if they hang around long enough.
