Some groups you say. I can not think of any group, who do not speak English if being asked. Also please give examples of other cities and country's where so many people speak English, while this is not their native language. What do you mean with the 'dominant dutch way'? I smell some frustration of not able to organize (in a lot of groups in Amsterdam) and that people are pointing their fingers to each other, while there is a lack of self reflection and selfcritic.
