What leftists like most about WWII is the sprit of massive collective action, coordinated and overseen by a government full of people they imagine to be like themselves. Global warming offers a similar prospect of massive collective action, this time across the whole globe, but again overseen by people like themselves, and this time with no nasty guns. If global warming didn’t exist (which it doesn’t), they’d have to invent it (which they did).
“...but again overseen by people like themselves, and this time with no nasty guns.”
Oh! You can bet that once control over the people occurs (with the help of guns) that guns will be heavily used to ensure that the “proles” adhere to the global warming dictates and rules...for once the people finally realize that the whole global warming thing is nothing but a scam they will revolt.
