There have always been apostates. May be the quantity has now increased...generally people want to be part of a successful club, If Muslims appear to be in trouble all the time and they do not have any victories they will lose people. Individually as well people burn out...they get into religion get too hot, and a few years down the line they are burnt out, they did not nourish their own soul and got into religious arguments about who is right and who is deviated. I think we are living through confused times with many dislocated and disenchanted people living through the turbulence of modernity, alienation, cultural nihilism and globalization..people search for something and fail to internalize the deeper spiritual values of Ihsan.
