A reader, who happens to be of mixed Sikh and Hindu parentage, emails me to say the following:

'In today's Guardian Timothy Garton Ash explains why we should be sympathetic and kind to Muslims who consider Osama to be a hero and make statements like this:

'I ask another Muhammad ("just call me Muhammad"), a voluble 16-year-old, about last year's bombings just down the road, at the Atocha station. Well, he says, he doesn't like to see people dying "even if they are Christians and Jews". But in this case, because of what Aznar did in the Iraq war'.

"Even if they are Christians and Jews" tells you all you need to know about the mindset of many Muslims in Europe, as though CHristians and Jews are lesser people, scum, like dogs or animals. The left in this country is unable and unwilling to face up to the fact that there is a deep poison in the ideology of many of its idealised and romanticised "oppressed" lumpen masses. It is unable to accept that no matter what they do, there will still be people utterly deranged by an ideology of hatred that no amount of wretched and pathetic self flaggelation will defuse.

'I have e-mailed you before and told you about the rancid, casual, rabid anti-semitism that I encounter on a regular basis amongst Muslims I meet in my life. Because I am Asian, have brown skin, they sometimes assume I am Muslim, and even if they don't, they are freer to tell me their inner thoughts than they would to a white person. It is a level of hatred that is Nazi like in its extremity and virtually universal. I have met some brave Muslims who are sickened by it, but they are a minority and would never challenge the status-quo hatred that persists amongst them, for fear of ridicule, contempt, and perhaps even violence.

'It is only now that I am putting two and two together, though, and seeing how this links into the sly and crafty anti-semitism within wider British society, the type of anti-semitism in the salons that Philip Roth diagnosed so well in his writing when he lived in London and moved in the circles of "liberal" London. For them, the religious rapture of Islamist hatred for Jews is thrilling. Coupled with the vilification of Israel out of all proportion to its crimes, we have a heady brew of hatred and bigotry that the useful idiots of the left either choose to ignore, or actively participate in.

'Personally, I think that Jews, and to a lesser extent Hindus and Sikhs, face a future of marginalisation in Britain, caught in a pincer movement between the Islamist political game and the pandering of the left to every whim of the Muslim community. Look at Ken Livingstone and his outrageous remarks all to court the Muslim vote. This is the future of Britain. It is a tragedy.'
