Just to be clear about my own personal stance about being labelled a serious sinner - quite similar to Jeff Windup merchant's:
wt: "We are not embarrassed about adjustments that are made, nor is an apology needed for not getting it exactly right previously,"
Me: I am not embarrassed about using 'independent thinking' to make needed adjustments in my thinking. Nor is an apology needed to wt for using 'independent thinking' to get right previous errors in my thinking.
