Greenpeace USA, a nonprofit that wants to reverse global warming by stopping oil drilling and coal burning, explains online why climate change "deniers" don't have a right to free speech.
"Don't the deniers have a right to free speech?" Greenpeace asks rhetorically on its FAQ page. Answer: Apparently not. "There's a difference between free speech and a campaign to deny the climate science with the goal of undermining international action on climate change," Greenpeace argues. "However, there's also responsibility that goes with freedom of speech - which is based around honesty and transparency. Freedom of speech does not apply to misinformation and propaganda."
Greenpeace makes the argument in the course of an attack on Exxon Mobil, a company that provides oil to the people who are "driving climate change by burning fossil fuels like coal and oil."
