In principle I agree with your text above, maybe my expression was mistakable. The whole thing is complicated. Regarding global warming we could say there are (at least) three groups of people:
(1) those, who are concerned
(2) those, who are not concerned - but practiced a serious information search before
(and came to the conclusion that there is no risk)
(3) those, who are not concerned - but consumed only one-sided information
(and only insist that there is no risk, without considering arguments of the other side)
The fist two groups would be o.k. (the fist group has to practic serious analysis too).
Problematic is just the third group. I am in group (1), which group do you belong to?
Nobody could blame them. As long as they disagree because they seriously thought about the issue - but in a non one-sided manner - nobody could blame them!
But I think there are many people who deliberately watch ONLY “climate change is a lie movies”. And they are intentionally searching ONLY for information that tends to “refute” climate change. No wonder that they are coming to the conclusion that there is no threat. Think about this: The “ONLY” is the problem here.
I do not say that you are (or someone else is) acting like this. But I say: If one would belong to group (3) and not to group (2) it would be a problem. And then the answer to the question “Who can blame them?” would be different.
Which documentarys do you watch?
It is not my opinion that conservatives should be worried about climate change!
It is my opinion that: If conservatives (or everyone else) reject global warming, they should have practiced a serious and not one-sided information search before.
If you consume information only from left-wing-greenpeace -> This would be a problem!
If you consume information only sponsored by exxon-mobil (or so) -> This would be a problem!
Maybe it is the case that most conservatives fall into group (2), and did their honest and not one-sided research. This would be great! But I think there are still al lot of group-(3)-people in the world, that consume only “there-is-no-threat-movies”, (cons and non-cons) - and these are not so sophisticated. How would you assess yourself? Type-(2)-person?
