Gilleard, a forklift truck driver from Goole, East Yorkshire, admitted to police and the court that he had held racist views.
At the time of his arrest he was a paid-up member of the National Front, the White Nationalist Party and the British People's Party - all opposed to multiculturalism.
I am so sick and tired of hearing nationalists talk of killing Muslims, of blowing up mosques, of fighting back, only to see these acts of resistance fail to appear
His computer password was Martyn1488 - the 14, according to prosecutor Andrew Edis QC, being a reference to the far-right's "14 words" slogan, "We must secure the existence of our race and the future for white children."
The 88, Mr Edis added, represented the eighth letter of the alphabet - an abbreviation for "Heil Hitler".
But Gilleard was not simply a passive crank, the court was told.
In a notebook recovered by police, Gilleard wrote that the "time has come to stop the talk and start to act".
"Unless we the British right stop talking of racial war and take steps to make it happen, we will never get back that which has been stolen from us," he added.
"I am so sick and tired of hearing nationalists talk of killing Muslims, of blowing up mosques, of fighting back, only to see these acts of resistance fail to appear."
In another note, he wrote that he wanted to see "reds" - left-wing activists - attacked with "lightning strikes" and "home-made grenades".
His comments were a chilling echo of far-right nail bomber David Copeland, jailed for life for murder after attacks targeting London's gay community and ethnic minorities in 1999.
