> Basically the whole point of the Freemasonry fraternity as well. Male only. It is dressed up with some altruistic goals and rituals

Freemasonry began as a workers' guild, but the accreted "goals and rituals" take a group far beyond the simplicity of a men's shed.

The simplicity of any club rapidly becomes complex when monotheism or henotheism (any theism) is injected:

From Wikipedia:

* Anglo-American style Freemasonry, which insists that a "volume of sacred law" should be open in a working lodge, that every member should profess belief in a supreme being, that only men should be admitted, and discussion of religion or politics does not take place within the lodge.

* Continental Freemasonry or Liberal style Freemasonry which has continued to evolve beyond these restrictions, particularly regarding religious belief and political discussion.

* Women Freemasonry or Co-Freemasonry, which includes organisations that either admit women exclusively or accept both men and women."
