Research commissioned by the Equal Opportunities Support Unit shows that many of the imams who are working in Flanders hardly speak any Dutch, the language of their local community. In addition, they are hardly in touch with the local community.
The research shows that most of the imams active in Flanders didn't grow up here and never learnt French or Dutch. They have little understanding of Belgian or Flemish affairs. As a result contacts with Belgian youngsters are strained. In consequence many young Muslim Belgians go in search of information about Islam via other channels increasing the chance of radicalisation.
