It makes perfect sense. He is supposed to be the expert and we, regular people could clearly see what he could not. What is confusing about that?
There is nothing arrogant about it either. FR posters do not bill themselves as political gurus. We don’t get paid for professional opinions and evaluations as he does. We are average people.
Average means just that. Average. You have to compare something to something else to get an average. But since you asked, No, you don’t have to be a freeper to be smart. Plenty of freepers prove that daily. Plenty also prove the reverse. Same as non freepers. Thus...wait for it...Average”.
Freepers are a tiny drop in the bucket. Too few compared to the whole to average out.
