Many times these groups takes immortal stances because of their detachment from reality. For example there is a huge correlation in people who don't care about the suffering global warming causes and religion. Its not really hard to understand either, many modern day american think Jesus will come in their lifetime, so why bother caring about 100 years from now.
It even works for things directly against rules in the book. Churchgoers are more likely to be for the death penalty even "thou shall not kill" is most of those religious books.
I am not saying all religious people are bad, just that religion does not filter out bad people or bad behavior effectively.
