For some, only their ideas matter.
In fact, for people like that, there's almost no use in trying to share ideas or have voice, because no matter what you say, their idea will trump.
This is problematic when people like this are leaders because that means few to no are represented in decisions, and when there is little representation, there is often little buy in or valuable success.
It is troubling to face situations like this in both small arenas and large arenas as large as a state or country.
