Is this not Off the Wall? Last I checked, anything could be posted here as long as it's in good taste.
This is simply a thread linking to a news story. You can tell by the title it's not going to be a pleasant story. No one forced you to read it, you choose too.
You might be sickened by the act, but asking for the thread to be deleted isn't going to make the fact that it happened go away. Use better judgement when reading threads if you want to avoid these kinds of stories, just like you would do when reading the newspaper.
