Choosing to be cruel is directly related to insecurities, as you illustrate with your honest essay.
Shannon Frandsen

I think a lot of it comes from fear, or at least that’s where mine came from. Fear that I’ll never be accepted for who I am rather than what I project, fear of failure in publishing, fear that I won’t have the life I want, etc., and I think out of the fear comes envy and resentment, and that could, coupled with insecurity, dovetail to the hate we see online.

It’s a good question, though. You’ve given me proverbial food for thought :)
