I come from a family of migrants. There was a time last century when most of my ancestors then living went to the other side of the world (to fight in WW2, or to flee from it).
I owe everything I have (not merely my possessions and freedom, but my life, my very existence!) to their ability to establish new lives for themselves in a remote place.
It's very humbling, really. Is it even possible to repay this kind of mortal debt?
It is possible, of course. And it's very simple. All I have to do is to treat migrants in the 21st century with the same kind of tolerance and respect my predecessors depended on for their lives in the 20th.
Possibly, somebody else might feel the same way?
