We have to be fair and logical. The natural and rational number should be 50% of divorces due to women initiating if its' fair. However, because its' 70% there is obviously some biases involved. Women are Hypergamous and without the Church curbing the Hypergamy of women and the Polygamy of men, there would be more infedility. In the past, when people were more religious there were less women riding the cock carousal and ruining the pair-bonding through sex by having multiple partners. The sexual revolution is responsible for the breakdown of families. And poor son or daughter have to endure a carousel of multiple fathers or mothers since their parents aren't as faithfull as their ancestors.
