YOU get a better class of political protester at Oxford University. Last week, when students broke into an Oxford Union debate to protest at the presence of the British National Party leader and a notorious Holocaust denier, one of the intruders commandeered a piano and shouted a question to the packed hall: "Wagner, perhaps?"
Free speech. A noble idea. But the debate about it in Britain today isn't really about free speech at all. It has become a Trojan Horse for a different debate entirely - one about religion and race. By deciding what's permissible to say in public, we
are defining how tolerant a society we are prepared to be. In practical terms, this means how tolerant we are of religious and racial intolerance.
For the majority of us, liberal by instinct and live-and-let-live by inclination, this throws up some uncomfortable conflicts. On one hand we have to decide what leeway to allow extremists to spout race hate. On the other we have to judge when to curb the hateful preachings of religious fundamentalists, both Christian and Muslim.
Last week in Oxford, Nick Griffin of the BNP and the disgraced historian David Irving were faced with protesters who seemed to be split into three camps, each with its own distinctive take on the right of free speech.
The first, echoed by a number of eminent commentators in the past week, goes something like this: Yes, these men have the right to free speech; but they are not entitled to make their loathsome case on such hallowed ground as the Oxford Union, which has played host to great historical figures including Mahatma Gandhi, Bobby Kennedy and Mother Teresa.
What tosh. If the Oxford University is indeed the apex of intellect it professes to be, then where better to forensically dismantle some bampot fascist ideas and show them up as historically illiterate, morally indefensible and politically naive?
The second group's viewpoint is slightly different: yes, we have a right to free speech in this country, but that only applies if your views are nice and cuddly and liberal, like ours. Otherwise, we will shut you up. If you want to preach racial intolerance then we will deny you a platform, we will deny you a debate and we will try to drown you out by shouting very loudly.
More tosh. By refusing to engage in debate with the extreme right - or any group that plays to base fears - all we do is nurture and sustain them. It's not good enough to say we're not going to dignify their views by responding to them. We must meet them head-on, always giving trust to reason and the power of argument. Anything else is a counsel of despair.
Of course, the right to free speech is never an absolute. There are laws in place to ensure that if BNP statements stray into incitement to racial hatred they become a criminal offence. But within the bounds of what is legal, free speech should mean exactly that. Even if it means the freedom to be racist, misogynistic, homophobic or any other intolerant social trait.
There was a third group at Oxford too, and their reasoning could be summed up like this: whether or not you have the right to free speech is irrelevant - you're a fascist bastard and I'm going to try my best to give you a good kicking. I admit in my student days in the early 1980s - the era of Rock Against Racism and the Anti-Nazi League - I may have had some sympathy with this view. These days I hope I'm more reasonable.
A useful rule of thumb is this: your fundamental right to free speech will only be curbed when it infringes on the fundamental rights of others. And there's an important distinction to be made here. There is no fundamental right to have your religious beliefs protected from criticism. Just because you claim your views are sanctioned by God does not provide you with any additional protection, or justification for that matter. This is what psychologists call a 'category error'.
At the moment, the novelist Martin Amis is being accused of being a racist because of his sustained criticism of extremist Islamism. His critics' reasoning appears to be that because most followers of Islam are non-white, Amis's views are therefore racist. At the risk of repeating myself: utter tosh.
Amis is exercising his right to free speech in the precise area where it is most needed - in seeking clarity in a debate about religion and race that is too often a fug of lazy assumptions and unexamined prejudices. His criticism is not of a race or a religion but of an ideology. He refuses to take the craven and cowardly position that we must accept other cultures and other traditions entirely on their own terms, without any reference to our own morality and values.
There's a phrase we're all familiar with, for which we can thank Voltaire: "I disapprove of what you say, but I will defend to the death your right to say it." Here and now, in Britain in 2007, this notion feels a bit antique. Today we are far more likely to say: "I disapprove of what you say, so I will accuse you of racism/religious intolerance/political incorrectness until you shut up."
It's time we rediscovered the spirit of Voltaire's original sentiment and applied it anew to the troubled age in which we live. Free speech, after all, has a price.
