One point that’s come up in discussion of the fire cataclysm is the fact that anti-vaxers are viewed with contempt, and subject to sanctions like “no jab, no play”, while climate deniers are still given respectful treatment, media platforms and so on. The explanation is simple enough: climate deniers are rich, powerful and numerous, including most of the rightwing commentariat and much of the government.
Although both groups are wrong, and present a huge danger to the community, it’s important to observe that most anti-vaxers (the exceptions are charlatans like Andrew Wakefield) are honestly concerned about the health of their children, and have simply latched on to misguided information. By contrast, as I said in this 2013 piece,
The difficulty is that the proportion of tobacco and climate “sceptics” who are honestly seeking the truth is far smaller, while the proportion of paid hacks and culture warriors is far higher. Members of the latter group will seize on any concession made to encourage genuine understanding, and will use it as evidence of weakness in the scientific position.
I’d update now to say that, almost without exception, climate deniers are paid hacks, culture warriors or both.
