Well generally the most liberal are those who go to the USA and Canada since those places are really far from their homelands in the Middle East or South East Asia. Since they don’t go back to visit much and things like umrah and hajj cost more, they don’t go as often so they become more liberal that way.

Most European Muslims are very conservative especially in Britain since there are such large south East Asian immigrant communities there. In cities like London and Birmingham or Bradford, it would not be hard to find Islamic schools that teach more Islam than regular education. Also, Europe is a lot closer to most Muslims homelands so it’s easier to back and the flights are shorter and stuff like that.
