I do not agree. I think the OP quote is rubbish, because yeah, many people tend to not think critical enough about opinions they claim to have. BUT this also feeds into "the people are stupid" and expertise of the elite arguments, that I dont support.

For me this just another nice sounding rhetoric that does not really have value in any academic form. I mean the only statement you make is "I could not agree with him more". So the only thing you conrtibute is the firm believe in something someone else said, which I guess is one of the implemented critics in the quote.

Just to be clear, I dont want to offend you or fight, I want to discuss ;)
