When you admit you haven't read his profile page you can't defend anything he has there.
When he admits he's an atheist, it is a lie for his profile to read Christian.
Wow, you are desperate to accuse anyone in sight. After you raised the issue about his profile page I went to it and saw that he had registered in 2011. I knew from talking to him that he used to be a Christian but after his son died he has withdrawn himself. That is why I said in a post that I suspected when he had signed up he was a Christian but didn't want to speculate. He has confirmed that is the case.
So then I do not see myself as "defending what he has on his profile page" only stating the obvious facts.
1. Did he lie on his registration? Apparently not.
2. Therefore the issue is not about lying it is about updating his profile page, neglecting to do that is in my opinion negligence.
3. He has openly stated repeatedly that he is not a Christian so I see no attempt at deceit, hence I stand by my conclusion that calling his profile page saying he is a Christian to be negligent as opposed to your calling it a lie.
However, I will agree that since making this big stink about it he should update his profile page and likewise you should give him a Private message requesting that he do so.
