There is a lot of unconstructive abstract grandstanding here. OF COURSE the Church is not going to shift its position without being forced into it by an utter catastrophe but's exactly what they're up against. (Most of the Evangelicals would probably not even shift their position confronted by the extinction of humanity, they need to be obliterated rather than argued with).

This is what Brazil's healthcare system is currently like:

Imagine trying do any of these in a mess like that:

- Zika infection testing
- foetal malformation screening
- coping with an infant that will never develop the higher mental faculties of a rat.

So, is the church going to do a damn thing about it? Bloody unlikely that its upper management will, but there are millions of its rank and file who know perfectly well that people don't have to live that way.
