The "okay boomer" era of the internet came and went. Idiotic to blame climate change on an 80 year old person when we know exactly who paid for and then covered up the data suggesting manufacturing and transportation was harming the planet and ourselves.
I don't blame them for not understanding 40 years ago, but I do blame them for not understanding now. Older generations still contain the majority of climate deniers and other heel draggers, and their votes make a big difference.
