As someone who is a former non-Christian, Christian Forums kind of steered me away from Christianity at first too. At first it was because I was non-informed and saw a bunch of threads that conflicted with my own beliefs (to me, it was all nonsense). Then it came from seeing people getting a bit hostile with each other for having different beliefs, or claiming that they were right while everyone else was wrong (and, let's face it, the truth will always be the truth, but there's no need to be so rude or snarky about it).
It got to a point where I took long hiatuses from this website a few times. What brought me back, each time, was talking with other Christians offline who were kind, non-judgmental, and not trying to forcefully push their beliefs on me. Through communicating with them and developing a sort of fellowship with them, I was able to open my mind and heart up so I could learn more about what Christianity really is. Then, God did the rest, and now I'm on my way to being baptized as a Catholic Christian!
But, getting back to the question, as an outsider, this website put me off from being Christian. It was only when I started to really learn about Christianity from offline sources that this website started to become helpful to me. When I learned more about it, I came here with questions and got some good answers. So, in one way, it made me want to be more of a Christian, but in other ways it didn't. But it mostly depended on where I was in my journey.
So, my final answer is: Undecided.
