Part 3  - most of America's white cradle Catholics are descended from Europeans. They were not welcomed by the original WASP settlers. The Irish were described in terms now used about Latinos.  But there were no immigration quotas at that time, nobody could legally bar them from entering this country.  People came here to escape poverty, violence and religious oppression - the same reasons people try to come here now. But it is much harder now than it was for our ancestors.  We are the richest nation on earth, we can afford it.  We became who we are because for centuries, including now, some people had the courage and strength to take the risk of moving to the US, the shining beacon on the hill, to start over with nothing except their own courage and determination. That is what has made America unique.  Now some people want to reject those who are coming here - for the same reasons as our own ancestors, people with the same courage and determination.  Welcome them, don't reject them.
