John T. Earnest, the perpetrator of an arson attack on a mosque in Escondido, California and a mass shooting in a synagogue at nearby Poway, stated in an open letter that he was inspired by Tarrant as well as Robert Bowers, the perpetrator of the Pittsburgh synagogue shooting. Following the Escondido arson attack, he had left graffiti that said "For Brenton Tarrant, -t /pol/", and prior to the synagogue shooting, he published said open letter on 8chan and attempted to livestream the attack on Facebook Live just like Tarrant. Earnest also mentioned in the open letter "The Day of the Rope", a talking point in white nationalist and neo-Nazi circles referring to the execution of all non-whites, Jews, and liberals, as detailed in the 1978 novel "The Turner Diaries".
