Yes Gray2023, America was predominantly Protestant at the time of women's suffrage, but the question should be, Did Catholic countries allow female suffrage too, and if so, did this fact affect their death penalty positions? Every Catholic country in Europe had the death penalty, England, Spain, France, Italy, Germany (Bavaria), etc. England did away with the death penalty in 1965, and allowed female suffrage in 1928. This theme is a constant, allow the female vote and we open the door for effeminate judges, effeminate politicians, and effeminate policies. And "no death penalty" is very effeminate. Today the death penalty is non-existent in Europe; there is no 2nd Amendment in Europe (excluding Switzerland). Europe has lost the Faith.
Thirty years ago a Catholic girl here in my home city decided to write a newspaper piece about the horrors of bodily punishment. I reminded her that our Lord hit people with a whip in the Gospel of St. John, and, of course God is in favor of capital punishment. He allowed it in the Old Testament and said nothing in the New Testament about its abolition. This girl followed her immature logic as a seventh grader, and I would bet that she is still doing so.
Here is a list of countries which have allowed female suffrage by year:
