Considering this , I being a believer in Christ Jesus, would stand with the atheist , as they would at least in a debate consider the teachings of the Bible weather they believed it or not. Simply for the book itself.
The Jehovah witness is already distorted in its roots, therefore would not represent it in its true content.
I would think the atheist with their intelligent and logical reasoning even thought a non believer would consider the character of the message set forth by the Holy Scripture, and present it in the light it was meant to be.
They would have no reason to distort it, as they don't believe it as truth, yet would still present it as it was written. If it was a debate.
Disbelief is better than misrepresentation.
