I encourage it in any field, even religion. The problem is that most of your 'free thoughts' here aren't original, nor are they very well-reasoned or researched. Thinking for yourself is about more than just hawking hatred and knee-jerk rebellion against an establishment. In fact, the athiest mantras you're repeating here don't show a lot of free thought--they show that you are as stuck in atheist dogma as you claim Christians are. I honestly have no problem with your atheism--just with the hatred and incorrect presentations of Christian beliefs.
