The church views the poor and those with health issues as people they can "help". This is how it has always been and they are entirely open about it. So I'd say this is kind of a non story.
Facebook was used as a platform for a well-funded campaign to identify ill and vulnerable people to bring them to extremist churches specifically for the purposes of political radicalization.
This is a step change in the level of 'wrong' from churches merely using Facebook-guided advertising to exploit vulnerable people for religious purposes.
I'm going to guess that when the church was recruiting executioners for the inquisition they weren't selecting for the most well adjusted people then either. And I guess you could call that radical politics.
Also please see the HN guidelines regarding insinuating someone hasn't read the article.
