As one of the offenders, I do not see it as that far off topic. If someone posted a video called "Parkour for kids", would you think it off topic if people pointed out that this is just a really, really bad idea?
Getting triggered by a title and regurgitating pre-existing bile about OO (of all things) in the name of protecting children (of all things) was, yes, offtopic and more than a little silly.
