Do people look at an aborted fetus flying above a city and change there minds? Or is just showing everyone a disgusting image to "confront" a percentage of people with their own hypocrisy/whatever?
I'm against tobacco (I call it cancerweed) -- but I wouldn't go so far as to fly an image of a lung full of carcinoma above a crowd to discourage smoking.
Practical reality is that there will not be any legislated ban of abortion in America or any overturning of
Roe v. Wade in the foreseeable future. The best that the Roman Catholic Church can ever hope to do is to promote a climate that cherishes life -- one that of course rejects aggressive warfare, economic inequality and insecurity, and capital punishment. All that the Roman Catholic Church has at its disposal is moral suasion -- but I'd rather have that than power that people hold in contempt.
