We used to care about people fleeing from oppressive cultures and governments. Now, we call them law breakers and unwelcome.
When we didn't, we were greater for it. America meant a second chance. We knew we could handle it. We had confidence in our own conscience and system of government. We didn't care how the rest of the world did it.
Now, we try to cut off those dreams. Those who do not already conform to our "standard" are not good enough for us. My ancestors didn't conform when they came to the modern day U.S. in 1620, but I'm glad they did.
As a genealogist, I've learned that immigration is the lifeblood of our free society. Without it, we don't really believe in freedom and justice for all.
