Re: You haven't got a prayer...or do you?
While I'm sure they'll say something to make it sound like they weren't wrong, I think it's safe to view this as a pretty clear cut case of them actually being wrong. They told someone to stop taking their medication, and then that person died. God didn't save them, prayer didn't save them. The preacher can dress it up however he likes, but at the end of the day, he promised something he didn't deliver.
As for bombing abortion clinics vs. hunger strikes, I have to see the comparison as both missing the obvious difference and fairly offensive. Bombing an abortion clinic is murder. It's killing other people. Whether some people feel its justified, or whether some religions feel its justified, it's unquestionably murder. Someone who engages in a hunger strike harms no one but themselves. To imply that they're on the same level simply because the person's faith may motivate both of them is a bit of a leap to say the least.
The question, in my mind at least, isn't whether people should be able to do anything they like if it's an "issue of faith." Their motivation doesn't really come into it. If you kill someone because you think God hates them, or you kill them because you personally hate them, you're still a killer. Freedom of religion is about letting people practice their religion on themselves, not about letting them practice it on others. The people who stopped taking their meds made up their own minds. The preacher who told them they should bears some moral responsibility for the death, but legally, the decision was up to the person who believed them. That's very different than if the preacher started breaking into people's houses and stealing their meds because he thought God would cure them. In that case he'd be practicing his religion on other's, and freedom of religion shouldn't (and wouldn't) protect him.
