It is only our knowledge and wisdom that separates us
My concern with the whole Geneva Conference on racism is how many countries boycotted the event - Australia, Canada, Germany, Israel, Italy, Netherlands, New Zealand, Poland and the United States. It's perhaps naive to think that there aren't occasions where people are forced into a boycott, but to not participate raises a concern about commitment to the premise of human equality. If we are divided because racism exists, then other struggles for equality - gender, cultural identity, religion and class will never happen. As someone anonymous once remarked: "There is only one race - the human race". The boycotting countries have a certain something in common - politically they are perceived as "white" and most yield influences that could have been exercised positively in the fight against racism.
I don't know of any society where there isn't some guilt or that hasn't had to deal with some kind of internal issues with race and racism, but there are historical examples of where entire social systems have been built on racial exploitation and legal division. These have tended to be in places where Europeans have held power, either as colonialists or in the post-colonial world. You'll find many European expats here in the Gulf enjoying a very privileged lifestyle, not accessible to the poor South Asian labour force.
Here from where I sit in the Arab world, there is a political perception of the Iran which is unique to the Arabs - reactions to Iran coming from Europe and the West are different. The subtleties of this are often not understood, but exploited into a "them and us" situation which is essentially anti-Iran, anti-Ahmedinejad and ultimately anti-Muslim. Isn't it precisely this very attitude that leads us towards the racism that we should be challenging? Iran - whilst not perfect, is what the West-leaning Gulf isn't; it's actually a multi-party system where universal suffrage exists for all people over 15. According to my last check, the current Leader of Britain, Mr Gordon Brown, was not elected by the populace and governments in the Gulf are almost completely made up of ruling families.
The conference may have been a sham, but that was due to other forces of distrust. Many may conclude that much of the non-participation was about a cynical desire to preserve the global racial inequality status quo and not just because Iran was there.
