As usual, AGW (Anthropogenic or man-caused Global Warming) believers refuse to recognize differences in opinion.
When honestly-felt doubt is cast in a negative light as one who is apostate in some bombastic religion, I tend to run away in the opposite direction. In other words, even if the AGW believers were right, I'd hate them anyway. I'd hate their evil slimy guts, because they don't seek debate and understanding, they seek to silence, destroy, and demonize anyone who doesn't agree with them. Take your Global Warming God and shove him sideways up your anal orifice, please.
Just because I have doubts that climate change is caused primarily by humans does not mean I doubt that climate change happens.
Just because climate change happens does not mean that it is unnatural.
Even if climate change is being caused by the agency of humans, that is no reason to believe that the agency of humans can stop it.
And most importantly - I don't care about climate change, whether it is caused by humans or not; with one exception. If the climate is going to change significantly in my lifetime, I will plan my activities to profit by it to the extent possible, and plan my retirement in climes that are now less expensive and more northerly so that they'll be expensive and toasty when I get there and I'll have bought cheap.
I do not care about climate change. It's useless hand-wringing at best and a waste of my tax dollars at worst.
A 'denier'? Please. I'm a realist. It doesn't matter and I don't care anyway. Believers; not only do I refuse to worship your God, but I'll urinate on your graves while spraying fluorocarbons into the air above them. Non servium, baby.
