I like Klein's proposal. Too often dissent is seen as 'trouble making' and put into a different category from leadership. I always wonder what is really going on if someone putting forward an idea is made more nervous by people asking questions rather than enjoying the opportunity to explain more.
Lots of things going on. Usually, if it's a small startup not enough time was spent thinking about the idea. In large companies, it's usually the result of an entrenched position where many benefit from that position and feel threatened if questioned.
