This behavior is one of the ways humans learn. We emulate authority, and we emulate majority. It's built into all of us, even atheists. I don't even find it sad. I do wish people would question more before emulating, but the emulating part, you do it ALL THE TIME, without even realizing it. The speed you drive is regulated by other drivers around you as much as the speed limit on a sign or your own conscious "choice". Half the things you do and like were probably learned in this sort of monkey see, monkey do sort of way from your family and in places like Kindergarden. Don't knock it. It's very important that humans do this, societies would not function without it.
Just teach people to question, also.
