Judge Mark Dennis said he believed Dymock was dangerous and posed a “significant risk of serious harm” to the public.

“It is clear you were a leader and not a follower,” he said.

He added Dymock was an “intelligent, well-read” person but also “wholly misguided.” He stressed that Dymock was “driven by an extremist mindset” and had taken the path of “total hatred and bigotry.”

Dymock’s trial last month revealed that he had used the SRN website and a Twitter account to state that Jewish people should be exterminated and to encourage lone actor terror attacks. He advocated for a “race war,” and called for gay people to be “purged” from society.
