The path of conformity and the path of reason are utterly different things. Therefore they lead to utterly different ends. Therefore if you find yourself in agreement with everybody then in all probability you have arrived at that other end and you didn't get there via reason.
Not contradicting anything you said or trying to make an argument, just thought it would be a cool thing to share and let people learn about.
But if you do want some kind of argument, then I would say that while you are not wrong here, conformity has basically nothing to do with drawing reasonable conclusions and that really isn't it's purpose. Conformity is almost more of a defense mechanism (which can go wrong rather easily, hence this discussion) meant to keep us comfortable and prevent accidentally painting a social target on our own backs. It's when conformity is conflated with logical reasoning that we start to get problems.
You make it sound quite linear. There are more than 2 ends so there isn't "that other end". Your social group might not see birds as dinosaurs but that doesn't make them governmental drones either
