This, but with evolution.
I feel you, but my thing with climate change is that inaction on it will actually cause human suffering (ie. famines, droughts, floods, heatwaves, etc....and in our lifetimes) whereas not believing in evolution is just stupid in a more general way. Plus we have a very limited amount of time to try to avoid the worst effects of climate change. So people's stupidity when it comes to climate change is actually screwing a lot of people over, especially in poor countries.
It's kind of a general stupidity vs. harmful stupidity thing...though I guess you could argue that not believing in evolution is harmful in a more subtle way.
