What do you mean by "are very selective on the protests"? I go to protests selectively and I don't believe I'm "stupid" so I'm confused by this comment.
Do stupid people know that they are stupid? I would say the majority of them think they are smart.
90% of people think they're above average drivers. And no, the flat earthers e.g. think we're stupid. I'm not sure stupid vs. smart is the right axis here though. Plenty of people with apparently high I.Q. believe in nonsense.
Well if you want to call me stupid that is fine, we can have that conversation, but I'm not so it won't be very interested. Bringing me back to my original question, a question that was actually interesting.
