those pesky "Sanctity of Marriage" people

This is what they say:
1 Man + 1 Woman = Marriage

This is evidently what they mean
1 Man + 1 Woman + Lovers of any variety = Marriage

BIRCHES has no criticism of the idea of loyalty in marriage. Millions practice it, and is honorable to do so. The problem lies with those who think they can lecture the world about morality and "defend" marriage, and call marriage "sanctified" and deny marriage rights to others, etc. --- and then go forth and screw their brains out in Argentina or in the supporting crew of their campaign committees.
