There is no theory. I demolished it with your inability or unwillingness
to address the evolutionary rates of split versus lumped genera. It was
not rhetorical, and while it was sarcastic, that was predicated on my
expectation that you would be unable or unwilling to answer it.

QED. I dismiss your remark because you have not provided evidence that
genera are generally non-arbitrary. You dismiss my remark by applying a
stock formula that you have used so often that I wonder if you have a

As you define it. QED again.

I find grouping by shared homology to be useful. You accuse me
(specifically, by lumping me with all cladists) of some sort of
structuralist heresy. I'm annoyed by that, and it makes me unwilling to
discuss things with you, since you have already made up your mind about me.
And now that I think about it, your grouping me with "cladists", absent
any expressed theory, seems rather structuralist. Perhaps you have a
theory. Could it be falsified by evidence from my actual intellectual
history, and the factors that shaped it?

To me, that is a meaningless question, since the rank of genus is (IMO)
in practice arbitrary.If you circumscribe non-arbitrary genera, then
huzzah. I'd be interested to know how you can repair the genera
circumscribed by others in order to make them scientifically meaningful.
If you can explain that, then perhaps we can move on to your question.
