Climate change deniers.
Is climate change bad? Very bad, existentially bad. Do I want it to happen? No. Do I try to take steps to mitigate it? Yes, I put my drop in the bucket and vote for people who support policies that would help.
But we're eyeballs deep in Brandolini's Law at this point and by the time we get ourselves out of the quicksand, massive change will have taken its toll.
I'm not saying we shouldn't take action, but working ourselves in to a spittle-flecked outrage everytime someone says something stupid on social media is a waste of energy when we're already in damage control mode. The battle lines have been drawn for decades and the backlash effect is a very real phenomena.
Economics is going to win this fight before logic and debate does.
I wouldn't mind hearing about him falling down a flight of stairs, being bitten by a rabid bat, or getting lockjaw.
