The election of two European parliamentarians from the far-right, racist British National Party in June has removed the cover on a political sewer that should have been sealed for all time.
BNP leader Nick Griffin, a man with a history of anti-Semitism and holocaust denial, now calls for "chemotherapy" against the Islamic "cancer" in Europe.
The echoes of the past are deliberate. The choice of words is chilling.
Griffin's election to European Parliament has given the BNP unprecedented access to the media, and he is using it to promote the most vicious racism.
His genocidal rantings towards Muslims followed his call for the sinking of ships carrying migrants from Africa to Europe — in other words the premeditated murder of men, women and children on a desperate voyage to escape poverty and oppression.
Almost 1 million people voted for the BNP in the European elections. If there is a cancer in Europe, then it is the cancer of racism.
Yet the response from the political establishment to Griffin's remarks has, so far, been less than overwhelming.
Defensiveness and political compromise have marked the response of mainstream parties to the rise of the BNP.
This is not a temporary blip before we return to business as usual. Ignoring the BNP or playing down their successes will not make them go away. It is time for the anti-fascist movement to go on the offensive.
Griffin's Nazi-style outbursts cannot be dismissed as an irrelevant excess by a marginal figure. He knows what he is doing. He wants to make legitimate what was once illegitimate.
He aims to shift the centre of gravity of political debate sharply to the right. He knows that his more extreme rhetoric is in tune with his party's membership and large swathes of his voters.
But he also knows that every time mainstream politicians bend to his agenda in an attempt to occupy ground he is staking out, the racist argument is strengthened.
It is a pattern we have seen all too frequently. Faced with a rise in racism, politicians seek to ride both horses at once: deploring racism while conceding ever more political ground to the far right.
Isn't this exactly what Prime Minister Gordon Brown was doing when he called for "local homes for local people"?
There are too few affordable homes. But that is because successive governments have relied on the market to provide what it patently cannot do.
What should be done is to tackle this policy failure, which would provide affordable homes for all those in need.
Furthermore, the Equality and Human Rights Commission has revealed that nine out of 10 social housing residents were born in Britain, giving a lie to the BNP myths bout "local people" losing out to immigrants and asylum seekers.
Instead of focusing on these realities, voters are told that their prejudices are justified and that the government will do what the BNP cannot.
It is a tactic both cynical and ineffective.
The response to Griffin's call to "sink the boats" cannot be one of pledging to do everything possible to keep out immigrants short of launching missiles at defenceless people.
His call for "chemotherapy" against Muslims must be challenged, rather than conceding fears of Islam in Europe are justified. The alternative is to accept that ever more extreme and dangerous fascist rhetoric will define political debate in our society.
Those who promote fear and hatred of African immigrants or Muslims have to be openly and directly confronted.
It is not legitimate to blame migrants or refugees for the recession. They were not the ones who became rich beyond anyone's dreams while gambling away our economy.
It is not legitimate to blame immigrants for rising unemployment. They did not close our factories and devastate our manufacturing base.
It is not legitimate to blame "outsiders" for the housing crisis. They are not the ones who passed legislation that strangled the ability of local councils to build new housing on the scale needed.
And it is not legitimate to scapegoat Muslims, who represent just 3% of the population, for any supposed threat to "British identity".
A recent Gallup poll on Muslim integration revealed that while only half the British population very strongly identifies with being British, 77% of Muslims do. And only 17% of British Muslims wanted to live in an area consisting mostly of people of the same religious and ethnic background as themselves, compared to 33% of the population as a whole.
Being "different" is not a sign of alienation from society as a whole. Yet more and more people conclude that Muslims are a breed apart.
There is a gulf between the reality of our lives and the perception that is created by a constant stream of horror stories.
Today, it is anti-Muslim racism that is at the cutting edge of the fascist strategy. It is effective because it feeds on the suspicion and prejudice that is the theme of so much mainstream discussion.
Its consequences are real. Already, there are signs that attacks on mosques and individual Muslims may be rising. The police are warning of the danger of far-right terrorism.
Earlier this month we saw an openly racist provocation in Birmingham city centre, under the guise of a protest against "Islamic extremism" — a label that the organiser made clear applied to all Muslims.
We, as British Muslims, have a direct and immediate interest in defeating this fascist threat. The anti-fascist movement must reach out to Muslim communities who are at the sharp end of BNP attacks.
But the rise in racism is not only a threat to Muslims.
The BNP may be playing down their anti-Semitism and anti-Black racism in order to drive a wedge between Muslims and the rest of society. But to the BNP, we are all "racial foreigners". Our very existence as British people denied.
We have to not only unite all those targeted by the BNP, with every possible ally who rejects racism and fascism. We have to also positively assert our multicultural and pluralist society.
It is a message of hope that is in tune in an increasingly interconnected world. It is a source of strength and vibrancy. We are one society and many cultures.
And we will only remain so if we are prepared to stand up and be counted.
