What if you don't speak English? Then the KJV won't be useful for you. The Bible was written in Hebrew and Greek. The KJV is a good translation, and it uses the right texts unlike some other versions, but it is not as if it is the last word in Bible translation for all time.

The Bible says, "Test everything. Hold onto what is good. Avoid the form of evil". There will be people posting things as comments which reveal ignorance and spiritual problems in their lives. We want to be able to help people deal with issues, and one way is to allow interaction with people who don't agree 100% with everything we think or believe.
