Why are we so mean?

I read non stop. anything I can my hands on History medical eighteenth century liturature, a few lovely fiction writers.  Imagine , if you will, my surpise when in reading an artical about a woman who chose to have her both breast removed after finding out she was positive for the bRCA1 gene, and whose mother how had died after a lengthly battle with ovarion cancer. She intended to have her overies removed soon after. Imagine that upon reading this my shock that one of the first comments was  "big deal, been there done that." several similar comments along those lines follow. We'll this post is very short.

One question. why are so mean?

Think about it.
