1. You focus too much on one aspect (Evangelicism) of one religion (Christianity)
2. There is no need to point out hypocrisy or inconsistencies in the Bible. We all know them, the only people who don't are people who aren't going to listen to you. Take for example, Genesis. Easy target, right? I mean, the whole God created the world in 6 days thing, and the talking snake tempting Eve, blah blah. Well, in case you forgot, this is from the Torah, it didn't originate in the Christian Bible, and how many creationist Jews do you see running around? Sure, there are a small handful, but I've never met one. Do you know why? It's because when Genesis is read in it's original language, it is immediately obvious that it is 100% allegory. Metaphor. So go ahead and tell a Jew that he is silly for believing that crazy story, and he will just shrug you off, because he doesn't. Not literally. When you just pound away on these sorts of issues, you're really, again, just focusing on one subset of one religion (see first point). If you truly wish to attack religion, you have to do some more reading and come up with something better than that.
3. Theology is an enormously vast subject, with a myriad of possible interpretations, forms and belief systems. Any objection you can come up with to belief in general has already been completely explored by serious students of it and thrown out and/or encompassed into a concept. Try reading the Talmud, there is a great example of that kind of work.
4. You really cannot invalidate someone's personal experience, and you will never know the nature of it. This goes for anything, but particularly for matters of the heart, of which religion/spirituality is a member. You look silly trying.
5. Don't become what you loathe and start preaching the Positivist version of philosophy. Hey, it might even be "correct", but isn't the thing that really turned you off from religion in the first place is the way that so many of them want to shove it down your throat? Grandstanding and self-righteousness are not solely the domain of religion.
Now, all that being said, I think the one area that Atheists have a real bone to pick is in the ignorance about it from religious minded people (again, specifically American Evangelicals). Try to focus on that, and remember, self-righteousness is butt ugly no matter what angle you are coming from.
EDIT #1: A caveat: I misspoke when I said that all of Genesis is taken as 100% allegory, what I meant was the Creation story specifically. There are certainly lots of viewpoints on this among Jews, however, the vast majority of them see no conflict with the story and modern science, because the vast majority do not interpret it literally.
