I do not call Tour a liar out of any personal, political, or religious bias.
He is a liar because he lies. I have documented him lying. I gave detailed sources. Some whined that I posted too many scientific citations. I simply listed some of the lies Tour told, and some people demanded citations.
Prof. Swamidass justified Tour lying because the nasty Atheists are mean to his friend.
If you look in the mirror, ask “Did I dismiss lying because I have a personal relationship, and he is supposedly of my faith?”
I retired, but I never as a scientist made light of any falsification of facts from a personal relationship.
