Here is a link to George Will's column "Scientific silencers on the left are trying to shut down climate skepticism".
Authoritarianism, always latent in progressivism, is becoming explicit. Progressivism’s determination to regulate thought by regulating speech is apparent in the campaign by 16 states’ attorneys general and those of the District of Columbia and the Virgin Islands, none Republican, to criminalize skepticism about the supposedly “settled” conclusions of climate science.
Four core tenets of progressivism are: First, history has a destination. Second, progressives uniquely discern it. (Barack Obama frequently declares things to be on or opposed to “the right side of history.”) Third, politics should be democratic but peripheral to governance, which is the responsibility of experts scientifically administering the regulatory state. Fourth, enlightened progressives should enforce limits on speech (witness IRS suppression of conservative advocacy groups) in order to prevent thinking unhelpful to history’s progressive unfolding.
Progressivism is already enforced on campuses by restrictions on speech that might produce what progressives consider retrograde intellectual diversity. Now, from the so-called party of science, a.k.a. Democrats, comes a campaign to criminalize debate about science.
