“Goo-goo” hucksters (self-anointed paladins for whatever “cause”) are prone to hyperbole, but when they stray into outright lies, things can get hairy. . .
The outright lies “Saint” Rachel Carson (she who is still much-adored in the enviro-whack community) have resulted in more human death and suffering than all the depradations of the worst mass murderers of the 20th Century—Hitler, Stalin, Mao—combined. Heck, her lies resulted in more than double the maximum number of deaths attributed to the Mongol Empire under Genghis Khan.
Silent Spring was, at the time, one of the most blatant examples of outright lies in its deliberate misrepresentation of the effects of DDT, yet today it would just be everyday, ordinary toxic sewage swallowed by folks feeding at the Hivemind Media trough.
