Online bullying

I am sat her reflecting on a couple of things with a tenuous connection that have had quite an emotional impact on me.
One happens to be the online encouragement of a person from another Tumblr community to commit suicide for what was seen as a slight on another communities member. The person concerned was a young Kidhearted member as I was until an incident lead to us parting  who has a number of mental health and developmental disabilities and as such I always kept an eye out for them
This is being condoned by a teen mod of the other Tumblr community.
Ya know this takes me back to English Literature, would of been about aged fifteen reading William Golding's The Lord of The Flies where a group of well educated English boys bereft of adult authority due to a crash separate into groups  in a downward spiral from mean-spiritness to outright savagery.
My problems with all this drama start with inappropriate moral equivalency in putting offence caused by a ill considered comment (and god knows we all can do it) with actually encouraging a person to take  their lives after taunting them.
They are two different things.
The other is the lack of tolerance which is not about agreeing with somebody but respecting the right of an other  to hold an opinion even one most would consider ill judged that soon leads into mean spiritedness.
This so often manifests itself in NIA banners or Non Interaction Allowed where people from one group are told because they either belong to a community on Tumblr or interact with one they don't like you cannot 'like', reblog from or comment from another because one says the other is wrong.
It means since what happened with me I cannot even post message of support for this person subject to the sick suicide baiting  because their community bans ours (although we ban none) from posting to them.
I am waiting for certain communities to grow up and  at least  agree to disagree on some topics and work together on keeping people really safe.
