From the article you posted: "During cross examination, Thompson went after her views on religion, which plaintiffs' attorney Eric Rothschild said went too far."
If ID isn't about religion, why would the defense go after her views on religion? It makes me wonder if these folks ever actually listen to what they themselves are saying.
It's incompetent lawyering too. Apparently Federal Rules of Evidence preclude attempting to use a witness's religious views to impeach his/her testimony.
