I understand your point.
You think that there is merit in going after a person and that there is little merit in going after their children.
My point is that both are the actions of mental midgets.
It's just the internet, if it upsets you, it can be switched off.
You're right: if any of the cyber mularkey were genuinely disturbing to 'bigmc,' he could simply disengage and carry on with life.
That said, feigning indignation gives him something to do. If it isn't harming anyone, why reign down on it?
