You'd have to ask them that. All I am saying is that those people
are out there, there are a lot of them, and (since they tend to be
old-timers) they are often in positions of authority and influence.
That doesn't (of course) mean that you have to agree with them; but
it does mean that you would be wise to be aware of their existence
and their opinions.
I am aware of pieces of doublethink like this one, if that's what you
I'm even aware of the attempt to create a "Biological Genus Concept" in
extrapolation from the two Biological Species Concepts (if there are or
can be viable hybrids, we're dealing with a single genus), but only
something like three people have ever advocated it, let alone used it in
anything near a systematic way.
And perhaps not to present your own as though they represent a
position that is universally held.
It's not just my own, it's the ICZN's: if you don't like an existing
classification, you're completely free to publish your own based on any
reasons or lack thereof you like, and neither is ever wrong.
