It's not that I don't see that happening but it's always from people I don't know and never talked to in real life or on the internet.
I have this strong feeling it's a loud minority. It's the same with real bullying, the bullies think they behave normal but the majority think they are bullies.
I think you're probably right. I think people don't necessarily associate ridiculing someone on the internet with bullying (in many cases because the target of ridicule isn't there interacting with them).
Sure me and my friends talk shit about people that has been exposed doing stupid things on the internet, but we do it in private. We don't ridicule in public. I think that's the difference.

edit: changed majority to minority:)
