The Blunt Amendment would allow employers to opt out of provisions of the nation's health care laws if any procedure or product violated the employer's religious belief (http://news.yahoo.com/...). While Democrats are centering their objections to the idea that it would restrict women's health care and specifically contraceptives, the amendment would go much further. If one recalls that the introduction of variolation, a forms of vaccination against small pox (http://whqlibdoc.who.int/...), was met with religious furor where many religious leaders argued that the scientific prevention of disease and death went against god's punishment of evil doers and his privilege to take and give life (http://en.wikipedia.org/...).
The Blunt amendment takes us back to the rule of ignorance over treatment of disease. Companies and employers could refuse to pay for children's vaccination on the same grounds or as is happening in California's Marin County, the idea that natural disease is better than vaccination.
