I was really surprised the hear of the hate crime, murder of three Muslim girls, by an atheist.
Looking at the below link, it can't see any evidence his atheism was the reason for shooting these girls.
According to the police report
On February 10, the Chapel Hill Police Department said their investigation indicates that the crime was motivated by an ongoing neighbor dispute over parkingAlso
Also:
According to his current wife Karen (who has also announced that she is divorcing him), he did not commit the shooting due to religious bias, but because of a longstanding parking dispute, and that he had problems with several other neighbors.
Atheism doesn't have 'doctrines' from old books that suggest killing 'non-believers'.
Unlike certain religions.
