On the ground, so to speak, it takes two to make a baby outside marriage. (Inside, too, but that’s a different point.)
But on the legal front, it’s overwhelmingly men voting on the laws, writing the regulations, and making the judicial rulings. How is this women’s fault?
It was asked on a previous thread on this topic, “Why do we let women vote?” My answer is, “So you can blame them for everything.”
