As one grows up and develops an identity it is frequently enough to fight against things. To define one as not like your parents, not like what the school officials want. But as one gets older more is demanded, more is required. A positive position on subjects becomes necessary to function in the world. Thirty year olds calling home to tell mom that they went out drinking and there is nothing she can do about it rather misses the point of being an adult.
This is how I feel about much of atheism at the moment. So what that religion is wrong and probably so? So what that you can not believe and still function as a real human being? What now folks; what now?
We can do and believe anything we want for any reason we want. So what are we going to do?
