Religion In our Courts- Parental Custody Battles

I recently read an article concerning religion based custody battles/rulings (http://community.nytimes.com/article/comments/2008/02/13/us/13custody.ht...).
In summary, the article talks about how religious beliefs of parents could be affecting the outcomes of custody cases throughout the country. In many cases cited in this article, religion did seem to play a major role in the argument and decision of the custody battle. This truly infuriated me. I am not saying that religion is the right or wrong path in life, but as long as presence or lack of religion does not hinder the well-being of the child, it should not be taken into consideration in the proceedings. Who is to say that Judaism, or Christianity, or Buddhism, or Hinduism, etc. are wrong to study? With that, who is to say that being atheist is wrong? As long as the child is being raised to be a good, law-abiding, and decent person, religious or atheist, the parent is doing their job. When the courts use religion as a point of determination, they have crossed the line of church and state, and are therefore no longer honoring the position in which they have been elected to. With this being said, I do believe that there are unusual circumstances, as seen in this article, in which the child’s well being should be taken into consideration. The one instance commented on in the article deals with a battle of the Amish religion versus our every day society. According to the article, the Amish believing parent wanted to take the child out of school at 8th grade, as to follow her religion. This definitely hinders the well-being of the child, and should thus be taken into consideration. Outside of these extreme cases though, religion should remain out of the courts. Let me know if you agree or disagree with my above opinions.
