They don't think we're open minded and understanding.
They think we're ignorant of how the world works, condescending, and irrationally judgemental.
I'm not saying this is how we ARE, this is just how they view us, and because they view us like that from the very start, there is no opportunity for meaningful dialogue.
It is bi-directional prejudice, and only by acts of understanding and patience and wisdom can that be overcome.
