Shooting and burying was wrong then.
It still is.
The alternative that society chose - mortal sin - is gravely wrong.
I fear society likes divorce.
We can do better.
I'm not advocating it. I'm saying that the sheer statistics over a century do not tell the entire story -- the conditions of society are radically different in a way that cannot be measured or compared. As another poster pointed out, more people are cohabiting now than in 1934, when it was only the worst kind of people who did that sort of thing. And then there's birth control and abortion. Truly, there is no real comparison, then and now.
