I agree it is inhumane, and once again, inspired by adherence to religious dogma, this time Catholic. Even were the political climate to change. the opposition is just as wedded to the Catholic church and its teachings.
There was quite a fuss earlier this year, over the plight of "beatriz". From an early stage in her pregnancy, the foetus had been diagnosed as having anacephaly, so that there was no chance any resulting baby would survive. Despite this, and despite the risk to this girls own health, the courts ruled she had to carry the baby to term, risking the death of the mother. It is a ridiculous situation, one caused by an inflexible law heavily influenced by the teachings of the catholic church.
This was an article at the time Beatriz made international headlines. Your article refers to her, 3T - says she survived her pregnancy, fortunately, although her baby, to no-ones surprise, died within hours of birth.
