Okay, so, here’s what I got on the Irish-American disconnect from The Invention of the White Race, Volume One, by Theodore Allen: parishes, press, politics, privilege/patronage, patriotism, and Protestants. The racialized privileges and benefits are obvious. Archbishop John Hughes of New York was proslavery; he had a huge influence. The Catholic press supported his views. Proslavery was considered patriotic. Protestants were abolitionists; some were anti-Catholic. The Irish immigrants saw the US as a backup to fight British rule in Ireland. And Tammany Hall/Society Democrats were proslavery and they assisted Irish immigrants with citizenship, political power, and other supports. The writer of the book wrote that prior to the Civil War no immigrant group was better positioned to empathize with and support Black people based on their history than the Irish, and that’s how and why they failed.
