Taking your last point first, rigorous testing *has* been done, and for the
moment, it (or at least some of it) supports monophyly of
But that's beside the point. The people on this list have not been attacking
your *conclusions*. Heaven knows, I don't blame you for doubting the
oviraptorosaur-therizinosaur connection. It may very well be incorrect, and
even if it is correct, it is not immediately obvious. No one is "drawing
definitive conclusions" here.
No, what upsets people around here is your *methods*: specifically, making
Pronouncements From On High about both phylogeny and taxonomy based on a few
specific characters from a few specific taxa, while refusing to consider the
totality of evidence (e.g. whether a character can be easily defined, whether
a character appears to have evolved so many times independently that it
becomes phylogenetically uninformative, whether a character may vary
ontogenetically or among individuals, etc., etc., etc.).
And, lest anyone question my fitness to sit up on my high horse, yes, there
was a time when I made my fair share of Pronouncements (see archives from the
1995-96 period)--some of which actually turned out to be correct,
incidentally. But I was in *college*, for cryin' out loud.
