Terry, I have read the article by Henderson and I think that your opening post misrepresents her paper and focus of research.
It appears, both from your title and your selection of text to use for quotes, that she is in agreement with the statements that you selected. The statements you selected from her paper were presented as opposing views to her thesis.
Henderson is not in agreement with the selected text - she is stating those things as pre-existing views in scholarly circles, and her paper is an attempt to correct those misconceptions.
The thesis of her paper is that the First Amendment legal cases that were won by the WTS were carefully planned, and that the WTS had a legal strategy that was not at all "accidental".
