I was also convinced that it would be a good idea to prove that the key disputed points of Christianity were in fact correct. I went on skepticsannotatedbible.com and the Atheism sub-reddit and compiled a list of arguments to refute. I couldn't refute enough of them, and so found myself in a conundrum. I ended up choosing to live in the real world.
Most of my close friends, however, are still from the Christian communities I used to frequent. I prod and poke them mentally a little bit. Its amazing to me how Christians can justify almost anything, as long as their community mostly agrees with them. I have a group of friends who go to church multiple times per week, and have no problems sleeping with their boy/girlfriends. I have gay Christian friends, Christian friends who are bartenders, etc. My parents would be livid.
Anyhow, I just wanted to point out that when I think back about my life so far, the part of it that scares me, was when I took my religion and decided that I had to take it seriously and do something.
