to tweak your tweak...
...you've just defined an agnostic. Which is what I am. An agnostic reserves the right to believe in God at some point in the future, if he should ever find evidence he finds conslusive. If lack of faith is the only thing holding you back, then you are an agnostic. Not an athiest.
On the other hand, if you are confident to assert that...
"There is no Baby in the bathwater of religion. Best to throw it all out. The human race is grown up now, we need neither Cosmic Santas nor Universe-spanning demons in closets. Time to put away out [sic] childish things."
...then you are not an agnostic but rather an athiest. And you do indeed use some faith to come to your conclusion about religion, since you cannot prove it.
