Thanks guys. Both good perspectives. I've thought about this too - and being Irish AND Catholic, well hell that's like guilt squared.
Uh…throw that off. Immediately.
I jettisoned that crap in 1982 when I graduated from St Mary’s and started going out with a Protestant girl.
her entire family was so happy and carefree and unencumbered by the black cloud that hung over my entire family of nine potato-faced Irish Catholic kids, that I said “nope , no more , that’s the life for me !”
It also helps you make rational decisions, firmer, quicker , easier, and with more conviction.
Like Doug Stanhope says “You got something that was passed down or onto you ? Pass it back !” (or stay a child forever)
(Also , forget whatever assumed “guilt” they raised you under - way more importantly, you wannna be associated with an org with that many heinous, documented evil deeds ?

don’t know you, but I’m guessing not)
And for the record, there’s nothing at all inherently “guilty” about having Irish blood. It all comes from the other thing…
Tell your mom “Fine, but this is the last time. If you were nicer, I wouldn’t really have a problem footing the bill but , you’re not , so I do…”
