I struggled to get past this line. Just because I am against the global warming and gorebull warming crowd does not exclude me form environmental concerns. When a person is wrong on their initial contention I find it hard to further see what they want to say.
The author is not talking about own thoughts there, he is talking about polls and stuff. The pollsters will often generalize that way in their questions.
I noticed that, too. "Global Warming" didn't get the job done. "Climate Change" has performed less than stellar. Hey! Let's try "Environmental Concerns"!
More people need to wise up and realize that this is an industry, with thousands of investors, corporations, researchers, pundits, "scientists" and all manner of other people (paging Al Gore!) depending on us believing them to keep the checks rolling in.
When they say "deniers," what they really mean is "those who would deny me my next grant."
