Why do I read things that make me cry? Because it needs to be done. The standard reaction to horror, fear, or pain is to flinch and look away.
It's one thing to intellectualize the pain of others, and another to experience the immediacy of the fight against despair being waged in other hearts than your own. Suspension of disbelief in fiction is made possible only through the emotional realization that others suffer as we suffer, that even if the circumstances of the story are fiction, the impact of it is real.
Without art to encode and transmit the human experience, we are at risk of developing a terrible disease: Failure To Connect. The spiritual malaise and general apathy hitting this country, MY country, are the forerunners of a necessary paradigm shift. Because my country does not cry, and it is falling sick. It always has to bleed to get better, and I know that. Knowing that means that I have to look at it. We are all accountable to ourselves for what we do with what we know. Inaction DOES imply complicity.
It hurts, and you cry. It's okay to flinch.
Don't look away.
