Well, that's one common part of the phase of moving out of religion. I went through a religion bashing phase myself that one could chronicle through my post history. It's very similar to the twelve steps program used by people who are addicts (though I won't conclusively say religion is addictive, I think most people can recognize similar characteristics). The first step is that one is powerless against god, and that is a bad thing. This step is often the longest and has a great effect on the person's understanding of both faith and the faithful. The disillusionment often leads to anger and resentment, which is more anger at self for being manipulated than anger at others for accidentally or purposefully manipulating. People lash out at religion using their new found perception of religion or faith. This is what a lot of people think of atheism: people who are angry at god or angry at the church. And it's true, a great many atheists can get stuck in the first step for a long time or even indefinitely. The problem, as I see it, is that this creates an unhealthy relationship with people basically on the singular topic of philosophy, which is really something one should put into perspective. Most atheists have friends or family members who are theists, and if your religious disillusionment leads to creating a rift between you and those you love, it's not healthy at all. Long term resentment could mean anxiety and anger, and these things can even manifest physically (heart disease, for example). As a liberal, I imagine it was easier for me because liberals have a higher ability for acceptance (but that's a different conversation). I don't have to approve of something to accept it. The second step is realizing the power of either self or science or reason, or some combination of those concepts, can be more powerful than the concept of god or religion. The third step is the active step away from god and turn your dedication towards something else as a central focus, like family, study, self, etc.
Okay, it's only three steps, but I feel like it's important to go through them all. There might be like 9 more steps, and I'm only at step 3, so I'll let you know if I find anything else.
