My assumption is that we weren't all born with the intolerance we may have for those we don't understand. But if we could understand what closes us off to others and deconstruct it, we allow ourselves the opportunity to take time to think for ourselves. When we make time to do this, we may just realise what or who we closed ourselves off to had never been a threat to our being at all.

The mind is a door, longing to be opened.
