These people are too stupid--or too lazy intellectually and morally--to comprehend the difference between the United States and some bloody dictatorship or banana republic. They are stupid enough to think that, if we had free elections throughout the world, people of undeveloped countries, who have never been able to govern themselves, would suddenly become responsible citizens.
Leftists/"Liberals" love to spew forth mindless platitudes--"I care about allllllll the people of the earth, not just Americans"--as though that gave them some kind of moral authority--and as though that solved all the world's problems--and as though their brainless recommendations would not lead to certain disaster.
Most people care about all the people of the earth. Most people also have sense enough to know that the "solutions" proposed by these leftists/"Liberals" are not solutions at all. The immigration disaster is just one example--and not even the best example. The destruction of the California economy and the horrors of the Soviet Union, Germany under National Socialism, Pol Pot's Cambodia, and Castro's Cuba are a few other examples. There are countless examples.
It is because of the stupidity and intellectual and moral laziness of our bretheren that we are all doomed to relive history--over and over and over again. And some of the stupidest and laziest are our "leaders" in academia, journalism, and the arts.
