I hate to break this to you, but there will be no "reform" Islam anytime in the foreseeable future, insha'allah. The so-called "progressive" Muslim movement reached its peak in the early 2000s before self-imploding; their leaders were too full of ego to be able to work with each other, and they were never taken seriously (in fact, completely rejected by) the orthodox Muslim community. No group has ever taken their place, and they have no significant web presence.
A few weeks ago, in a report by the Royal Islamic Strategic Studies Centre (Jordan), entitled "The 500 Most Influential Muslims - 2010," the authors broke down the worldwide Muslim population by both doctrine and ideology. The ideological divisions are as follows: Traditional Islam, Islamic Fundamentalism, and Islamic Modernism. The authors described Islamic Modernism as follows:
Islamic modernism is a reform movement started by politically-minded urbanites with scant knowledge of traditional Islam. These people had witnessed and studied Western technology and socio-political ideas, and realized that the Islamic world was being left behind technologically by the West and had become too weak to stand up to it. They blamed this weakness on what they saw as ‘traditional Islam,’ which they thought held them back and was not ‘progressive’ enough. They thus called for a complete overhaul of Islam, including — or rather in particular — Islamic law (sharia) and doctrine (aqida). Islamic modernism remains popularly an object of derision and ridicule, and is scorned by traditional Muslims and fundamentalists alike.
Of the three groups, Islamic Modernists make up the smallest percentage worldwide, at 1%. Traditional Islam come in at 96%, and Islamic Fundamentalists at 3%. (The Sufis, called "Mystic Brotherhoods" in the report, are classified (correctly) under Traditional Islam.) The Modernists have no standing to influence the Muslim community, whether in the US or any other country.
If you want to encourage the positive aspects of Islam, you must deal with orthodox Muslims. This is not simply a case of conceit or real politik, it is simple fact as verified through academic studies. A recent study (January 2010) by researchers at Duke University and the University of North Carolina (Anti-Terror Lessons of Muslim-Americans [pdf]) found that, rather than increasing radicalization, mosque membership actually helped to reduce radicalization by working on community building. Moreover, that
"This research reinforces the generally accepted observation that Muslim-Americans with a strong, traditional religious training are far less likely to radicalize than those without such training."
Likewise, a 2008 study published by the Harvard Kennedy School (Estimating the Impact of the Hajj: Religion and Tolerance in Islam's Global Gathering ) found that:
...participation in the Hajj increases observance of global Islamic practices such as prayer and fasting while decreasing participation in localized practices and beliefs such as the use of amulets and dowry. It increases belief in equality and harmony among ethnic groups and Islamic sects and leads to more favorable attitudes toward women, including greater acceptance of female education and employment. Increased unity within the Islamic world is not accompanied by antipathy toward non-Muslims. Instead, Hajjis show increased belief in peace, and in equality and harmony among adherents of different religions.
So don't waste your time pining away for "reform" Islam; it is we orthodox Muslims whom you must talk with.
