I hadn't heard about Yoochun's thing at all, but I'm going to open can o' wormies and say I agree with this comment 2/3rds down the Omona page:
Okay seriously the fact that they call that a 'beating' pisses me off so much.
Fans and anti's can stalk these celebs, follow them everywhere, not give them any privacy, scream all kinds of shit at them, grab them, harass them, videotape them everywhere they go but if they ever slip up ever once they're suddenly women beaters and terrible people.
Being stalked is not fun.
Being constantly harassed is not fun.
Yes he is in the wrong for raising his hand to another human being but seriously these fans or antis or whoever are out of control and have been for years.
The first video of all this mess is down wherever it's been linked, but these people are batshit and I can't even begin to imagine how fed up I'd be after 13 years of it. The first video is apparently where the worst of it happened, so I might drastically change what I think about it after seeing what everyone's calling the "beating" part of it.
Doesn't make it right, but these insane people have had this coming for a while since it's only a matter of time before people snap.
