I have been following this discussion with interest, I am a great believer in the concept of critical thinking, the problem is that it is a specific skill that takes time and effort to master, even when you have tried to master the concept, ego and conditioning can quite easily result in less than constructive thinking.
In several suttas, the Buddha warned against this with the phrase "is a thicket of views, a wilderness of views, a contortion of views, a writhing of views, a fetter of views. It is accompanied by suffering, distress, despair, & fever, and it does not lead to disenchantment, dispassion, cessation; to calm, direct knowledge, full awakening, Unbinding."
Some of recent posts are, I think, veering toward this warning, it is important to incorporate discernment / critical thinking into the investigation of what Buddhism means for you, as has been pointed out there are a lot of dead ends you can travel along, these are often not in accordance with the Buddha's advice in the Pali Canon.
For me it is always a balance between a discerning intellectual investigation and a mindful awareness of the present moment effect of my actions, a middle way.
