Ah, let's see - truth by the consensus of professionals in a relevant area of expertise actually trained to analyze, interpret and review data properly, or truth by consensus of Gourmet Dan and the Discovery Institute. Tough call...
You mean 'the consensus of self-serving bureaucrats supported by public funds who have to kiss up to other self-serving bureaucrats to keep the money rolling in'. The true 'professionals' get kicked out if they depart from the party line.
But, you needed to support that 'truth by popular opinion' position somehow, now didn't you?
