Dr. Mann doesn’t seem to know who he’s labeling as a “garden variety troll”.
This is probably just a conditioned reflex on his part, since anyone who disagrees with the omniscient Mann is eventually labeled a troll, but in this case, Dr. Mann’s annoyance gives the extra distinction of “garden variety troll”. Observe:
Um, I think Dr. Mann doesn’t recognize a fellow PhD when he sees one, and surely you’d think Dr. Mann would recognize the co-founder of Greenpeace. Apparently not.
I guess Dr. Mann took exception to the “sensible” part.
UPDATE: A tweet by “AndyMac” is worth mentioning here, especially since I witnessed Dr. Mann and others decrying the poisonous atmosphere that apparently is all the fault of “deniers” at a special session of AGU 2013:
@wattsupwiththat Mann seems to split his time thusly…
1) Complain about abuse, etc, in the media/journals.
2) Abuse, name call on twitter—
