I don't see why people find it okay to insult idols/celebs. Yet if you were in school and insulted someone, you'd be in trouble for it, or you just wouldn't do it because it's wrong. What's the difference? Famous or not, they're humans too.
They do that because they feel like they have power in the internet. Disguised under a username, they can say whatever they want and not be attacked for it physically. =/
