There’s an interesting group that was recently formed, the Council of Ex-Muslims of Britain. Other European countries (Germany, Netherlands, Scandinavian countries) also have such councils, formed by and appealing to secular people from Muslim backgrounds.
This short speech by Maryam Namazie is particularly interesting:Such groups appear to defend an aggressive, affirmative sense of secularism. I am very sympathetic to such a view, but it perhaps works better in the context of countries such as France rather than Anglo-American political traditions. And it’s too bad that this sort of secularism is on a sharp decline in the few Muslim-majority countries that had been inclined toward secularism.
