[Taxacom] Taxacom Digest, Vol 187, Issue 18

"Here's another predictable example of garbage biogeography. Garbage,
because ...
...maintaining the fiction ...
It's all a total fabrication, now verging on fraud ..."

Even if people were marginally sympathetic to panbiogeography, the over the
top language would harden their stance. What you are complaining about,
again, is that they are using
timing to discern between tectonics and active dispersal. We already know
the "all-vicariance-team" has no room for the latter so... what's new?
