Yes, understood. I understood Betty Cunningham's post to be a comment that
our current cladistic procedures don't seem to produce generally agreed
upon "objective" ( <= big scare quotes) cladograms.
Therefore "something is wrong with our current procedures", or something is
wrong with our expectations.

I understand these particulars to be the topic under discussion -- and the
item about which general agreement seems very unlikely.

"Hypotheses" which many seem to take very seriously indeed.
