Call it my late Cold War childhood, but I've always found the term comrade thrilling in a slightly transgressive way. Which make the Order of Universalist Comrades, a national men's organization, so appealing. Appealing, but evidently short-lived.
Like similar women's and mixed young adult organizations, its goal seems to have been fund raising and wholesome entertainment, in the mold of then-more common city clubs, and may have been an outgrowth of freestanding clubs.
But without documentation, it's hard to say. Will keep an eye out for references.
And perhaps an opportunity to consider the next wave of men's organizations.
