What I did get is that the opinion of any other Grand Lodge as to co-mason regularity doesn't matter since it is only the regularity of the co-mason Grand Lodge that matters to the co-mason GL. As it should.
EXACTLY COACH !
This is why I thought Karen's essay won the prestigious prize it did, because it explains that. The prize was sponsored by the (very "regular"!) United Grand Lodge of England's Pro-Grand Master, Lord Northampton.
It made me understand "regularity" with a clarity i did not have before Bro Karen gave me some schooling.
"Regularity" is like club rules. What is acceptable in one club is not acceptable in another.
Mainstream "Regular" Freemasons sometimes carry on about what happens in clubs they will never visit, have a shared heritage with, and the ironically often wish us well (and will receive us as visitors though we can't visit because of our own rules).... Frankly many regular Freemasons vilify and persecute other Freemasons, because they're not in the same club. It often feels akin to Christian persecuting Christian because they're different denominations.
If you want to understand the concept of regularity - read Bro Karen's article without getting hung up on her gender or title. Regularity is the product of each Soveign GL much like law is the product of each Sovereign Nation State. What's legal in one state can be illegal in another and as Freemasonry instructs it's members to abide by the Law of the State in which they reside, so should we abide by the Law of our own GL's.
