Ummm... this writer, who says "What is happening to Saudi society?", grew up in a Saudi society where something like this was unheard of, obviously, hence his consternation that something has changed. But Saudi society was
never Christian! Even when roving bands of young men harassing regular people was unheard of.
Nope, it has nothing to do with the Lord Jesus Christ, personal saviorship, etc. etc. His presence or absense just isn't part of the equation here.
