Corky, interesting post and I hope to meet you some day - just for the record, you say "the idea of aikido as nothing more than a practice of self-purification as Janet suggested, if that is the way you want to see it..."
I apologize for this as it is tangential but cannot leave this unaddressed: I do not read anything in my words to come up with such an interpretation, and it is certainly not how I view aikido as my worldview specifically rejects a concept of sin or soiling that requires purification.
I do believe that my post specifically addresses the desirability of attacks that are martially meaningful, as in shomenuchi that induces nage to practice strong irimi.
My humble apologies for my misinterpretation of your words, Janet! I hope to meet you too some day. Mark Freeman speaks so very highly of you and I love your perspective (hopefully accurately understood!) that I see in your posts.
