What if it's on topic? Say, I dunno, when discussing climate change and citing a celebrity that won a noble prize for their related work?
I'll whole heartedly agree if you want to lay the failing at the feet of ever giving Gore the time of day in scientific circles, let alone a Noble prize. You'll have to forgive people for continually bringing Gore's statements on the matter forward though. His videos are showing up in schools to 'teach' kids about the important scientific research on climate change. My kids came home having watched before they were in grade 5. When the indoctrination is pushed that far out, people are NOT remiss to start pushing back.
IMO it's not much different than the situation with Islamic Jihadists and moderate Muslims. The fact some might claim common cause with a larger group doesn't make it so, but some denouncement from the greater community starts to become of importance. Regrettably, there has been little to no efforts made from the scientific community to distance itself from Gore's extreme proclamations and warnings. Yes, I know scientists don't appreciate having to come out of their research labs where they are doing actual real work to do stuff like that, but it's important. It's all the more important the more impact you believe your research has to society as a whole.
