It's so unfortunate that, with the onset of technology and anonymity, that both men and women have lost respect and dignity for themselves as well as others.
It's entirely too easy to be a complete shit bag on the Internet; we all know that these people would never back up this behavior in real life.
Not quite sure what the driving motivator is, nor where people believe they are entitled to act this way toward others with complete disregard toward the other person.
As I had that happen to myself often on Facebook, I got off of it and am much happier since then. I'm not saying that's the answer you should take, just what was easier for me.
Good luck…
