Angry racist Billy Charlton's true colours were revealed during a series of rants while being interviewed by the police.
During his trial, he tried to portray himself as a reasonable man who only wanted to protect women.
But jurors at Newcastle Crown Court saw through his lies and convicted him of five offences of stirring up racial hatred.
After his conviction, Northumbria Police released audio of his police interview, during which Charlton repeatedly lost his temper and ranted at female officers who were calmly trying to interview him.
During the trial, the court heard Charlton, who spoke alongside far right extremist Tommy Robinson on one occasion, hid behind the cloak of respectability of wanting to protect women from sexual assault.
But his true intention was to disseminate hate-filled falsehoods about immigrants, Asians, black people and the police, the court heard.
Prosecutors said his words sparked incidents of violence and damage by others attending the marches, including an occasion in which two innocent Asian men were attacked by a group of white men.
Jurors were told about footage from a "white man march" on Newcastle Quayside at which Charlton spoke.
The footage showed other people chanting things such as "white power", "Hitler was right" "sieg heil" and "keep it white", the court heard.
Charlton, 55, of Byland Court, Glebe, Washington , also made sickening references to the Grenfell Tower fire - saying "it's not cheap cladding that raped (a female)" and adding it's "immigrants who are a threat to our children".
He was found guilty of five charges of stirring up racial hatred and faces a prison sentence on Friday.
