Mean-ness

I am saddened whenever I hear or read a mean remark, and it is very alarming to see how it is growing in the social networks. Aside from their meanness, some comments are downright obscene and discriminatory.
Why?
Why do we mistake being "myself" or being sincere with being hurtful?
Why do we consider witty a comment that is downright insulting or rude?
Why do we call "hypocrites" people who try to think first and consider the consequences of their words before blurting them out?
Meanness never helps anybody. It just pollutes society with more anger and defensiveness. It is divisive. It doesn't foster sincere and caring relationships. It makes people downright snobbish or forever lacking in self-esteem.
Let us be kind.
If ever we have been a victim or a witness to meanness, let it stop with us.
Let us make this  courageous stand. Indeed it is courageous because it shows the greatness of our heart that doesn't indulge in pettiness.
