Ignorance is just a light that has been turned off inside of someones brain. 

You cannot turn it on for them.  They have to do it.

The switch is accessed by compassion and empathy. 

The best action that we can do for those with the switch turned off is to facilitate situations where they have the opportunity to be compassionate and empathetic.  Oh wait, I think that is called ‘life’. 

Still, we can encourage each other.
