Jumped down your throat? It's more likely that they simply disagreed with you, and for good reason: Other advertisers have reported that content ads work better than search ads, either across the board or for specific campaigns. So who's right, you or those other advertisers?
Generalities are like averages: They don't mean much in real life. Every advertiser and ad campaign is different, and what works in situation A may not work in situation B (and vice versa). That's why testing was invented. :-)
Still, there's one generality that most people here would agree with: Parked domains aren't "content sites."
