Of course we are. We fight over opinions and go to war over them and the outcome as a bloody battle and some fights are way to stupid to even fight for. We are dumb nitwit stupid things that were born into this world with thumbs. And I like thumbs. They're nice. And that explains why I'm an idiot.
The amount of knowledge we know compared to the huge amount of knowledge of our universe in many subjects, skills and languages is really small.
Yes, we have the ability to think and reason but yet we still do things that are considered idiotic by some people such as asking random people on the internet if they agree that we are all idiots.
