I don't find it acceptable to budle up issues of creationism/evolution and climate change. Writer is being devious when he's doing it so lightly as he did; especially when climate change wasn't mentioned in the title.
Hardly. The Lousiana law also made allowance for "supplemental material" on climate change, and Kopplin himself mentioned that "We don't just deny evolution... We are denying climate change and vaccines and other mainstream science...". Evolution denial is in the title but climate change denial is not because evolution is the main issue Kopplin has focused his activism on.
