Why are there so many...?

Why are there so many people who like to impart their "brainpower" to the rest of the world? So if a kid is hurt in school and it was not his fault, the answer is "he should watch where he is running" or "accidents happen". I thought this forum was useful but instead, it clearly proves how insensitive and cold people are. I am not surprised. I'm logging off now, I am sure that many of you are the same idiots on Facebook who spend their life online as philosophers.
