@DeeTee shared this article with me last night, and it was a breath of fresh air. You can also access the Twitter conversation between Sarah and the person who called her a c**t.
Her strategy is similar to mine as a blogger. I've been trolled by conservative Christians throughout the years. When this happens, the first thing I do is go to their blog (if they have one), read their about page, and may spend several hours reading their blog posts and comments.
Many times, I found that these believers with trolling behaviors had bad childhoods, had been indoctrinated with shame and unworthiness, had physical or mental disabilities, and/or had experienced significant trauma. They were projecting their pain. Some wrote posts about attempting suicide. Reading these posts and about pages guided me on how I would react and reply (if at all) to their demeaning comments directed at me or fellow non-believing bloggers.
I replied with compassion and empathy, and while some remained in denial about their pain or fears and justified their derogatory comments, others were softened and became more respective to the information I shared.
As you read the Twitter convo (embed in the article), you can see how quickly his demeanor changed and the flood of support that followed. A little awareness and compassion can go along ways and may even change a person's life.
