The Clifford article is entitled “A critic emerges from academia, Michael Carragher”.
It seems that Carragher is an academic (his college and discipline are not specified) who wrote something that was wrong on the internet in 2011. A print-out recently came into Brendan Clifford’s hands and the article is a belated reply. His reference to CLR was actually a compliment of sorts: the next sentence after the passage I quoted reads “But it wasn’t as bizarre as this stuff.”
