I am 75. I appear to be in my late fifties early sixties. I have heard the expression before and used in past occasions. Because I had pictured your name as a male (from the way you argue obstinately over Catholic issues), I had mistaken you for a male. I stand corrected.
When it comes to religion, I believe that the only thing I’ve personally argued *obstinately* has been ‘live and let live’. There is wisdom and good in just about every major religion - and in some not-so-major ones.
When I can’t personally believe in some point of a doctrine, I say so; and sometimes I suggest alternate exegesis. I think that’s just called ‘freedom of expression’.
Here’s to your own.
