I see myself as a climate change skeptic and a skeptic looks at the evidence and bases conclusions on the evidence rather than on belief. To hold the view that this is not an issue that you need to do something about, to hold the view that it's all a furphy takes belief.
I would say that there are a lot of people who currently disagree with the death penalty, I just hope that it's never one of their family members that is killed, because then they will probably change their mind on capital punishment.
