Yes, and did Irish Catholics ever invade and settle in other countries, threaten to take over entire countries by a certain date, stone a
teenage girl to death because she was raped by a male cousin, have clitoridectomies done on their daughters, etc. etc. Want more of a list?
To be perfectly correct, my Irish ancestors (male) did invade northern England. It was inhabited by Celtic Picts at the time. However, when the Irish Dal Riada left the island of Ireland, a famous Irish king stated, 'let them go, but may no one call them Gaelic again'. I think that means we were no longer considered Irish once we left. As what would later be called Scotland was settled and fought over by the Dal Riada, Christianity entered from Ireland and the pagan Dal Riada mostly converted to Christianity for the first time.
At any rate, I refuse to fly anymore until the Feds get their heads out of their rear ends. Have personally already given up quite a few free flying offers. And if Irish Catholics had declared holy war against the US and had blown up and hijacked some of our planes, I would have no problem with giving them extra scrutiny.
Damn Anglosaxons took over Dublin!
Damn Irish took over Boston!
Damn Italians took over NY!
and the NY Celtics cheated to win the 1929 NBA championship by recruiting a alien physical type uniquely suited to basketball.....the Jooos!
See, racial or religious stereotypes change over time. Imagine what the Romans said about the darn Slavs. Or the Celts, Or the Germans. Oh, we don't have to imagine, we can read what they wrote.
