Whatever philosophy you believe, I believe that everyone has the propensity for cruelty. When you become part of a scholarly or publishing community, you will encounter people who are selfish and overtly narcissistic. It may seem as if these are the only types of people that exist, but I assure you that amidst them are the enlightened individuals there for the art not a desperate grab at recognition. Just be aware that somewhere alone the line you will meet these people, and it will be easy to feel surrounded by their negativity.
The best way to circumvent these types is to remain calm and be prepared. They’re like ten year-olds at recess. Their only purpose by attacking you is to elevate themselves emotionally and in the eyes of their drooling spectators.
