Happy Saint Patrick's Day to all our Irish readers, our Irish-American readers, and to legal immigrants from Ireland. (As for illegal Irish immigrants, you can buy a one-way ticket from New York to Shannon fairly cheaply.) In honor of St. Patricks's Day, check out St. Patrick’s Day Explained To England by Peter Brimelow, and The Camp Of St. Patrick and Ganging Up On America by me. Peter Brimelow's column was an attempt to explain the St. Patrick's Day parade to the readers of the London Times in the '80s, and mine attempt to explain that nineteenth century Irish immigration was not an unmixed blessing.
