That large numbers of people threaten to murder retail workers for having a rainbow in their store suggests there's a bit more to it than "the internet".
Seeing people getting upset at nothing is always fun to watch.
Who decides what's nothing or what isn't? Shall the bully be the arbiter of what is pain or what counts? Can people just say anything and if you don't like it its your problem?
On the internet you can simply turn off the device and stop listening.
Nothing is in the eye of the watcher, neither arbiter nor bully, presumably.
I really like the showdead option this site has, and wish more sites used a similar setup.
