I do not believe that Islam is interested in such métissage, especially in the countries with a Muslim majority, eg., Jordan, Palestine,Tunisia.
Islam is a confident and serene culture which does not feel the need to be enriched by further contributions. This is why, paradoxically, perhaps the solution could come from Europe, where Islam is, for the first time, stimulated by the continual contrast with a non-Islamic majority and is forced to create for itself a pluralistic, open and inter-cultural world. In Europe, in contact with a pluralistic society, Islam can get rid of quite a lot of junk. Here, in secular Europe, another question to be asked is about the training and selection of the imams. The fact that the imams come from the fundamentalist colleges of Pakistan, Algeria or Indonesia cannot find us unaware or uninterested.
