So...
Polygamy!
I've discovered that the problem with researching this sort of thing (polygamy) (the subject of which I am speaking) is that everybody has an agenda!
It's like vegetarianism: all you hear is from the militant extremes ("Meat is Murder!" "Vegetarians are Sissies") and it's hard to find a balanced viewpoint!
Have you tried reading multiple sources and, then synthesizing your own viewpoint?
You are reading about polygamy, after all.
You know "more than one partner" ... "more than one book" ...
Polygamy!
Polygamous READING? What's next?
Eh?
"What's next?"
