Atheists are all really just fence-sitters at heart. Am I wrong?

I see more and more atheists coming out of the closet these days and they all seem to have a stick up their butt. Maybe they are all really just sitting on the fence and it's starting to get uncomfortable. If you really have no religious belief, then why spend so much time and energy getting angry at people who do have faith in something more than this. Are you envious you can't be more open minded to accept the possibility of something non-physical being in control of your existence? Or are you just afraid that if you accept it, it will become a reality you aren't ready to deal with? If this is all there is, then why not ignore all the religious chatter going on around you? Also, why are atheists particularly hostile toward christians? You say they attack you with their beliefs, but I have never experienced such attacks and I am not a practicing christian. I have been the religious "swinger", if you will, and from my experience the hostility comes from the fact that you really don't "know". It just becomes easier to settle with no religion because you're too afraid to give yourself to something non-tangible. Too afraid to open yourself to the unknown.
