A change of tune

Before Section 132 was included in The Doctrine & Covenants in 1876 there was another section that addressed polygamy specifically. It was Section 101 verse 4 (later Section 109), now edited out. It explicitly called polygamy a crime, denied its practice in the Church, and clarified that a man should have only one wife and a woman should have only one husband.

Apologists rest their defense of Joseph Smith's and early leaders' practice of polygamy despite scripture commanding against it on the fact that polygamy was not generally practiced in the Church, and/or that Oliver Cowdery wrote the now removed Section 101 as a statement of belief that was then approved by the ignorant masses of General Conference and not a revelation to the prophet. So why didn't Joseph repeal it, like, ever? Or at least modify it?

Why didn't the Church redact Section 132 in 1995 when it released the very monogamous-sounding Family proclamation? Or why didn't the Church at least include a more obvious polygamous family option in the proclamation so as to be true to its current doctrine? It all seems a little dishonest.

Call it sanctioned by God, call it evil, ignore it, either way it's coming back to hit you.
