Rush Limbaugh et al. are quite fond of intentionaly misunderstanding science.
Ozone at ground level is very bad (fries the alveoli of the very young and very old). Ozone in the stratosphere is good (blocks UV). Limbaugh et al. say "well, make up your mind is it good or bad?"
Shit heads.
Similarly, global warming at sea level is very bad (70% of the earth's coral has died in the last decade, yes, look it the fuck up, 70 PERCENT OF THE WORLD'S CORAL HAS DIED IN THE LAST DECADE). Oh, but at cold temperatures, cholorofluorocarbons persist longer in the stratosphere, so make up your mind - is global warming good or bad?
Shit heads.
A little like "heat is good because it cooks food, but heat is bad because it burns flesh when applied by napalm, so is heat good or bad you wishy-washy liberal"?
Shit heads.
(Not necessarily you Doug Chadwick - tongue-in-cheek is a possibility?).
