Potaterhater - you see AJP Taylor as having a right wing slight? I must admit I never got that feeling from reading/studying his work "The Origins of WWII" at A-Level. I admire that work very much as it looks beyond the idea of Hitler being the only cause of WWII and seeing it very much in context with the end of WWI, Versailles and the economic conditions of the early 30s.
Revisionist history like this has a lot to offer as it goes beyond looking at "obvious" causes of conflicts and will look at the wider context of conflict/events.
As for Irving, I personally feel that all this trial did was highlight his work and bring him fame. He's not an important "historian", has no real bearing on historical circles and his theories are easily ripped apart. As for the actual imprisonment of him, this is where the idea of freedom of speech and responsibility to humanity comes into question. Should freedom of speech unabated be allowed even if used by "extremists" to incite strong feelings against other groups of people? I'm not sure I know where I stand on this as it is a very emotive subject.
Out beyond ideas
of wrongdoing and rightdoing,
there is a field.
I'll meet you there.
All I possess in the presence of death
is pride and fury
