"A few who are relentlessly stupid, biased or paid to do this"
Worse than that. There is at least one 20 per day poster on here that is clearly seriously mentally disturbed. No matter how much evidence and logic you present him with it will have no effect. Those with a propensity for this behaviour have been turbocharged by social media, extreme right wing biased press i.e. Murdoch, and a few shock jocks.
None of us has the time or inclination to rebut all the posts. They are so extreme that no rational person would be influenced by them.
Outside this tiny minority of fringe dwellers there are hopeful signs of change. No better example than the head of BHP recognising an existential threat from AGW.
We will likely see some real action as the signs become even more obvious.. RWNJ's like Jopo, MrT etc are a minor distraction.
