If you grew up in the Boston area when I did it was all on display.
I worked for a Large Utility in the area and was cursed out by a follower of one of my mothers cousins, He was a Pol, clan system, for being a very Right Wing Republican, got very nasty.
I pointed out to him that my mothers family were Scots Protestants until one of my clan got a stiff pee-pee and married a papist.
I’m not talking about Boston Irish-Americans. I’m talking about the Irish of Ireland.
