That's pretty extreme, but perhaps not far off the mark. Probably they should just be sued, like the tobacco industry was sued for damages.
Since climate change extreme weather is already causing us 100s of billions in damages a year now, suing those who falsely argue that anthropogenic climate change isn't happening and work towards continuing the same behaviour, taking money from fossil fuel funds to spout disinformation is reasonable.
For idiots like moviefan, who aren't smart enough to know they are being suckered, public shaming should be enough.
But for those who take fossil fuel money, like those who publish moviefans talking points, they should be held accountable for some of the damages they are supporting.
Moviefan, who seems to buy into conspiracy theories, as he showed in his attacks on the media at the start of the Ford Gawker story.
