You have gone to a lot of trouble Nuisanceposter, and everything you have posted is correct.
I guess what I take exception to is your emphasis on the "willingly". I probably haven't explained myself well enough, but I did not intend that any of those quotes you uncovered in your search to imply that Patsy was 'willing' in the true sense of the word.
It was more a case of Patsy not being up to the task of taking a strong stand and saying "No" at the very beginning, when JonBenet was first abused which I beleive was by Patsy's own father when Patsy herself had just come down with ovarian cancer. Then as time went on, when a close friend started abusing JonBenet also, Patsy becoming more and more deeply compromised, a situation that the pedophiles well knew and understood and used against her when they needed someone to write a ransom note after they had accidentally killed JonBenet.
So I suppose I could agree that Patsy "willingly" wrote the ransom note, but by then she knew JonBenet was dead anyway, and she most definitely did not want John to learn of the prior abuse because he would most certainly not listen to any of her excuses as to why she had ignored it, and would most certainly divorce her and get custody of Burke. So she was 'willing' in a kind of blackmail situation.
As for the "knowingly", this again is hard for me to explain as I am not a psychologist, but there is something about a person being 'in denial', where they 'know' at some deeper level of their subconscious, but keep it suppressed so that at their conscious level it is not 'there'.
