I thought I knew what Christianity was, growing up in church. After I attended a theological seminary, I realized I knew nothing. Also I stopped debating religion with people online because I realized majority of religion debates are extremely shallow, yes even those with popular sciences like Richard Dawkins are shallow.

On the other hand, being just a regular member of my church, I also don't want to bring my background when I talk with my church community. Majority of people don't have the education that I had, and to explain half-assedly will just confuse them more.
