The FBI just released its 2018 Hate Crime Statistics report which documents the demographics of victims and suspects of crimes in the United States, at least when the motive was made clear to law enforcement. These aren’t all crimes. Just crimes that were based on someone’s gender, religion, sexual orientation, etc.
While any number is too high, of the 7,120 incidents documented by the FBI in 2018, “anti-atheist” (or anti-Agnostic) sentiment was the cause of only 6 of them.
By comparison, anti-Semitism motivated 835 incidents while Anti-Black hate spurred 1,943 incidents. Anti-LGB hate was the basis for 1,196 incidents while there were 142 instances of anti-transgender hate.
I should also stress the obvious: this isn’t some sort of Biggest Martyr game. No one deserves to be on the receiving end of vandalism or physical violence because of his or her religious beliefs, no matter how much anyone disagrees with it.
