O is that so? A very simple example: what are people saying when they are suddenly in a very bad situation and need help? Oh God, please help they say. Who is taking care of the people when there is a crisis, for example in iraq atm. Where are many refugees sitting right now? In churches. Who is feeding them? churches. Where are old people going because they know they will die soon and are scared and need something to hold on and what gives them stability? atheists and believers? They go to churches.
You cannot just say that religion is a hypocrisy when you think you don't need them, but then taking advantage off them when there is a crisis. Also, you can't just make something disappear what seems to be not useful anymore, but that has done so much for our society allready. Then go ahead, make your grand pa disappear as he has been working and paying taxes before, but now he is retired and maybe not useful anymore, he is just a burden really.
