3 years ago, I was taken and they poured acid on me, plucking me with blades. For hours, I could do nothing but scream as I burned. And then they would come back and do it again. Eventually, I was found by EMTs, and I did have to take me to surgery. I'm still healing from the ordeal to this day, and I might be permanently disfigured, but it's barely noticeable and mostly in places my clothes cover. Those wounds still sometimes bleed, and they ache.
When you're being tortured, the pain isn't what's unbearable. I felt the pain shooting through my body, so much so that I couldn't think or focus on anything other than the pain. As they knicked me and insulted me, I barely noticed. The hard part is being left alone with your anger for them, or your sense of powerlessness where you're still trying to control a situation that gives you a significant advantage. It's not the pain, it's when you're left alone. The pain, no matter how bad it is, is bearable. It's your mind that turns it into torture.
Do you believe that Martin Luther King, Jr. offered the other cheek in his protests as an insult and a dare?
