A satirical article on the web site The Science Post caused confusion in early 2018 by claiming that a new law allowed atheist health care providers to refuse to treat religious patients:
A new law in Mississippi has made it legal for doctors and nurses to refuse care to certain patients on religious grounds. The law allows medical staff to refuse treatment to members of the LGBQT community on the grounds that it violates their religious beliefs. It would serve to reason this would also pertain to atheist doctors and nurses who could refuse to treat patients who are religious.
I'm a physician and I think the state medical boards would revoke the license of someone who did this and it could be proven (same for religious doctors who refuse to treat atheists). Even without that, this agnostic doctor wouldn't even think of denying care to someone for disagreeing with her.
Of course it's satire. If atheist medical professionals were allowed to discriminate against the religious, they'd be losing their minds, and we'd ALL be hearing about it. They are the only ones allowed to discriminate against those who don't share their delusions.
It's a regurgitated satirical article that originally came out in April of 2016 in response to the right to discriminate law that passed that same month/year in Mississippi and is still in effect. In Mississippi, the government cannot take action against therapists or medical professionals for refusing to provide their services if it violates their "sincerely held religious beliefs."
