In this clip
, the author of On The Immorality of Illegal Immigration
describes how a visit to his old parish in Harlem reversed his opinion of open borders. Friends took him on a tour, where he saw how cheap foreign labor had literally changed the face
of the iconic
black neighborhood. As Father Pat remarks, "In all these shops the kids were taking me to, I hardly saw one black man."
The reason was that illegal foreign workers had taken jobs that had earlier been filled by African-American citizens. At that point, which he calls an "epiphany",
he began to realize that illegal immigration is not a victimless crime.
