I won't speak for Nathan Natas, but I will give my opinion of what he said, relating it to the article posted.
If accordance with reality is expected, even demanded, in so many aspects of our daily lives why shouldn't we be equally demanding of the accuracy of what we accept with regards to religion?
To simply say that it's ok to believe whatever we want to and then put lives and quality of life in jeopardy because of those beliefs is not acceptable.
Is it ok for Jehovah's Witnesses to sacrifice their children because of their interpretation of Scripture regarding use of blood?
Total tolerance would say it's their business.
Is it ok for Sharia Law to prosecute victims of rape and stone adulterers?
Total tolerance would say that's ok too.
