Suppose you're a Christian living in Mexico. Do you complain to God that your standard of living isn't satisfactory and that you deserve better? Do you make the decision to disobey the laws of the U.S. and cross illegally into the U.S. in hopes of fleecing U.S. taxpayers and receiving U.S. government entitlements meant for their citizens? Sure, you're willing to pick crops or do landscaping or house cleaning for low wages. The same type of things you did back home. As a Mexican Christian, why didn't you visit a local government office and fill out a form and apply for a work visa? Then work your way through the legal process of becoming an American citizen.
The difference between the left and the right in the U.S. seems to be that the left feels our borders and our laws can be ignored, while the right feels we have offered foreign immigrants an opportunity to become guest workers and permanent citizens if they merely follow the immigration laws. What you call gestapo is nothing more than law officers enforcing existing laws and sending criminals back to their country of origin.
In regards to Donald Trump and his viability as a Presidential candidate, I keep thinking of the following exchange from Casablanca;
[about Rick]
Major Strasser: You give him credit for too much cleverness. My impression was that he's just another blundering American.
Captain Renault: We musn't underestimate "American blundering". I was with them when they "blundered" into Berlin in 1918.
Donald Trump at times appears to be blundering. We all can see that. Yet he is clearly leading in the polls. Why? The conservative American voter has been supporting conservative, experienced, thoughtful candidates like your personal favorite, John Kasich, for many years and they have not seen the results they hoped to see. Government is not smaller. Deficit spending has increased. The debt is out of control. Immigration has not been slowed and illegal immigrants are being offered amnesty. Voting for typical Republican candidates, for many people, is voting for the status quo. People want an outsider who will shake things up, no matter how absurd they may seem. Trump and Carson are leading precisely because they are not experienced politicians who have failed voters. They are clearly flawed people, but they are tapping into an electorate that is fed up, unlike you, and wants something different.
