They have a long tradition of it:
"Less than a month after Columbia University gave Holocaust denier, Iranian president Ahmadinejad, a platform in the name of freedom of expression, the Oxford University debating society has contacted Holocaust denier David Irving using the same argument and asked him to participate in one of the society's forums in November. The club also wants to invite Belarus dictator, Alexander Lukashenko, and chairman of the British Nationalist Party (BNP), Nick Griffin.
Debating society president, Luke Tryl, told the British Guardian newspaper that the Oxford Union debating society "is famous for is commitment to free speech" and that the three had been invited despite their "awful and abhorrent views" He argued that the students at Oxford are intelligent enough to challenge and ridicule them....
Last month Irving told the Guardian that his views on the Holocaust have not changed at all and that his views have become stronger over the years. In several books he plans to publish soon, Irving maintains that "the Jews are the architects of what happened to them in the Second World War" and that the "Jewish problem" has been the cause of most wars in the past hundred years. Irving also claims that the gas chambers in Auschwitz never existed and that the camp was not an extermination camp and has only been publicized because it was well preserved.

"Stirring the possum" (saying deliberately provocative things mainly for amusement) is a popular tradition in Australia too. And if students cannot rebel against conventions, who can? I think Irving is mainly a publicity-seeker these days too. What he says does vary a lot from time to time.
