What is odd is that many African Americans ignore the reality of this racialization.It really hit me in the 1980s while living in Boston. At that time the southern Irish economy was a complete mess. People were the greatest export from Ireland, and a lot of them were coming to the USA. At the same time, immigration from Haiti and the Dominican Republic was increasing, and into Boston these three groups came.
Documented or undocumented all three groups found themselves looking for work and housing. As a struggle for the rights of immigrants and against discrimination emerged, Haitians and Dominicans began to coalesce, but the Irish were a bit stand-offish. Immigrant rights activists were at first perplexed until they uncovered that the Irish were being encouraged by Irish American politicians to keep themselves separate from other immigrant groups because it was likely that a ‘special’ deal could be cut for them.
To put it another way, the Irish were being trained to become and accept becoming white.
