For me (and for many folks), denialism is characterized by an insistent — and in some cases even compulsive — embrace of polarization and motivism, typically accompanied by rudeness, abuse,
ideological litmus -
testing, scapegoating, enemy - listing (etc.).
As in most of these cases, the treating of PG / CRU hacker by their own community can be used as a
litmus test to determine how far one's moral compass has been bent by their
ideological views.
