A British National Party activist has claimed a decision to ban him for life from teaching sets a "dangerous precedent."
Adam Walker was struck off by a conduct panel last month for verbally using three schoolboys, chasing them in his car and slashing the tyres of their bikes with a Stanley knife.
But the married father of two, who has worked with the far-right BNP since 2006, claims his "career has been taken from under me" because of his controversial political views.
Adam Walker has been banned from teaching for life
Speaking from his home in Durham, the 44-year-old said: "It sets a dangerous precedent. We're talking about the realms of thought crime."
Mr Walker appeared before a conduct committee in 2010 after it emerged he had labelled some immigrants as "savage animals" and claimed Britain was becoming a "dumping ground for the filth of the Third World" on an internet forum using a school laptop.
He admitted using the computer to make the posts but denied the comments were racist.

BNP Westminster Protest
The conduct panel imposed a conditional registration order and he was allowed to remain on the teaching register after he was cleared of racial intolerance but found guilty of misusing the laptop, which constituted unacceptable professional conduct.
The decision proved controversial, with the now defunct General Teaching Council (GTC) facing accusations it was failing to combat racism.
Following an unrelated hearing on June 19 this year, a senior official at the Department for Education ruled that Mr Walker should be banned from teaching indefinitely after a conduct panel heard he had verbally attacked three youngsters who had been asked to leave a fun-day at a pub in Tudhoe Village, Durham.
Mr Walker, a karate instructor, said he had held his "hands up" and "made a mistake" but claimed the decision was "totally disproportionate".
While the Education Secretary does not make these decisions himself, Mr Walker insists Michael Gove "used his power to reflect his own politically correct views".
He went on: "What I make of it is it may not necessarily be someone like myself - it could happen to anyone who might hold any type of views that do not fit in to the politically correct way of thinking."
He added: "We may have teachers who are on the extreme left wing, who attend demonstrations against people with my views, we may have Muslim extremists in the classroom. It sets a dangerous precedent. We're talking about the realms of thought crime."
Mr Walker added: "I have never taken politics into the classroom so I don't know what Mr Gove's hang-up is."
He said: "We often here about the right to a family life. We often hear about human rights with regards to right to work - that has not been applied here.
"I will never teach again in a British school. My career has been taken from under me. I have a wife, two small children and a house."
Mr Walker said he intends to take his case to the High Court.
He said: "I don't know how I'm going to do it as it appears that justice in this country is just for the rich, but I will fight my corner even if I have to represent myself."
Mr Walker was initially given a suspended sentence, disqualified from driving for a year and ordered to pay compensation.
The conduct panel accepted that he had recognised his behaviour was unacceptable and vowed not to repeat it.
But it added that the activist's actions had been deliberate, and despite being provoked he had "failed to maintain the high standards expected of a teacher both in and out of school".
A senior DfE official overruled the move and decided Mr Walker should be banned from teaching indefinitely.
He said he had taken into account press reports and publicity about the success of students who had attended Mr Walker's karate classes.
In his decision he said: "I do not believe however that the panel has taken sufficient account of the issues relating to the wider reputation of the profession.
"Mr Walker's actions, although provoked, were violent, threatening and targeted at young children. His actions were deliberate and resulted in custodial sentences, albeit suspended."
He added: "In combination, Mr Walker's convictions involved threatening behaviour and criminal damage of a serious nature, compounded by the fact that it was aimed at children. The reputation of the profession would be seriously damaged by allowing a teacher with this combination of convictions to be able to teach again."
