In a humane society, where women are not treated as second-class citizens and all life is truly valued, the way to be pro-life is to be pro-choice.
That does not mean making abortion — in some, many or all cases — legal and just standing back to “trust women” to work it all out for themselves. No, it’s a much heavier lift than that. But it is doable.
Being truly pro-life means actively working to provide women — and men — with choices, choices given to individuals that lead to a society with many fewer unwanted pregnancies, fewer women who have to face those pregnancies alone, with no support, no prospects, no other way out.
