TBH the shaming of Irish American pride follows hundreds of years of Anglo indoctrination of repressing Irish pride, from the language to traditional customs. Growing up as one of those Irish-American cats, the sentiment of an outsider in America and a distinct sense of identity.
Lets not forget, for a very very long time being Irish was a bad thing here, much of the sentiment shown towards Syrians was extended to the Irish, and honestly it was worse. I mean, the Irish and Irish-Americans fought alongside the Mexicans in the Mexican-American War (something I take pride in as an Irish-American), kept the Provisional Irish Republican Army afloat, and an Irish-American was the first true president of Eire after the Anglo-Irish War.
I find it interesting, anti Irish sentiment does still linger despite it not being so obvious. My heritage is brought up by strangers around five times a day at a minimum. An Irish-American can be a caricature of Irish culture and people go "aw shucks" (honestly it's why I get away with being the way I am) but the moment you're proud of it or someone from Eire you're labeled Plastic Paddy.
I think it's important for Irish Americans to remember what they've done for America, from being buried alive in the canals of New Orleans, uniting the country with Chinese immigrants, forming the Fighting 69th in the Civil War, Fighting as the San Patricios in the Mexican-American War, and "No Irish Need Apply".
Irish-American history is a distinct and important part of American history, and the story of the Irish people evolved after the great diaspora besides being strictly on Eire.
It's why I think White Pride is so fucking dumb, each European culture has their own distinct impact on American society and to concentrate on skin color diminishes each culture.
