● Chaser: Chuck Todd Bans ‘Climate Deniers’ from Climate Change Special:

Chuck Todd gave a stunning example of the phenomenon this morning in his introduction of a Meet the Press special edition on climate change. Todd quite literally announced that dissent would not be tolerated. Here was Todd:

“Just as important as what we are going to do this hour is what we’re not going to do. We’re not going to debate climate change, the existence of it. The Earth is getting hotter, and human activity is a major cause. Period. We’re not going to give time to climate deniers. The science is settled, even if political opinion is not.”

Note segundo: As Oren Cass has written at National Review: “The epithet ‘climate denier,’ intended to invoke Holocaust denial, has always been tasteless and inapt . . . But climate activists delighted in defining their opposition this way.” Chuck Todd should know better than to engage in this kind of ugly name-calling.

NewsBusters, today.

Just think of Todd as a former and current Democratic party activist, now with a byline, and it all makes sense.
