I spent my childhood in an imaginary world - probably because I needed an escape. I think that's one of the reasons people have imaginations - because they can't maintain existence here.
I believe in Christianity, Judaism and Islamism, but I stay away from churches, synagogues and mosques.
Even in the Western world, one cannot argue that the ideal has been achieved given the existence of issues like the integration, participation and representation of Muslim citizens, and occasional but lingering anti-Semitism.
