Steve2, it's funny that you took it as a loaded question. I actually thought it was a question by someone that did lose their faith and is now without any type of religious faith. I don't think the term "lose your faith" is degrading. Non believers commonly like to say that they have no faith. Then believers get into the tried and untrue "Well you have faith in the sun rising, so you have some sort of faith" argument that we all know does not work.
However, if someone did have faith before, and now they don't, then they lost it. I personally wouldn't think that saying "I lost my faith and am now an atheist" would necessarily allude to something negative.
