Religion indeed does turn people away from theism or even "God" (however we define God), but there are quite a few of us out there that are not your typical Richard Dawson, Science vs Religion, atheist. Rather we reject theism on philosophical - what we, others might of course disagree, would consider "logical" - grounds.

We consider a "God" to be an outright impossibility and that we can know this for certain. Some call this "hard" or "absolute" atheism, to name some labels I've heard thrown around.

Yet I'm certainly not going to force that on you. In fact for the same reason, which is to say philosophy, I personally hold that in order to be good I must let you think for yourself. It's rather similar, in a sense, of how most Christians wouldn't want to force anyone into Christianity. It would be a self-defeating exercise of trying to enforce ethics by unethical means.
