FtR, I was not in doubt as to why anyone would think the GOP is increasing its anti-Semitism.
Dettelbach seems an unlikely target for the label "anti-gun activist," given his career as a federal prosecutor and his strong endorsements from law enforcement -- support from the National Sheriffs Association and the International Association of Chiefs of Police.
Enforcing existing laws, as the main duty of your job, hardly seems like activism. Sort of like saying the director of the FBI is an "anti crime activist."
