Most people are not psychopaths. Most people understand the pain inflicted on the innocent fetus who had no choice about his/her mother's decision to get pregnant with the intent of killing him or her because she didn't want to bother with contraceptives. To those of us who understand these things, it is not at all inconceivable that support for abortion as birth control continues to drop.
In fact, the official stance of Boyd’s current religion, Unitarian Universalism, is outspokenly in favor of unrestricted abortion rights.
I was more-or-less raised in the tradition (?) of Unitarian Universalism. It's not a real religion. It's an anti-religion, existing to somewhat fill the needs of those who need that structure, without actually providing it. It's like eating tofu sausages to trick oneself into thinking that one is eating real meat. It falls short of being satisfying.
Barack’s maternal grandmother (who raised him) was a Unitarian.
