The beauty of online discussions I think is that there are technical solutions that don't exist in real life. In real life you can't always avoid a bully because they can follow you and get in your face. But here if I thought someone was bullying me I would just put them on my ignore list. After that they could go on and say whatever they want but what I don't read doesn't really hurt me does it?
Then there would be only my own morbid curiosity to deal with.
