Not sure what confused you. It's a rhetorical question using essentially the White Houses "incitement" argument.
The WH, just like you me, the GOP, ze Germans, Al Qaeda, whoever are all free to request that YT review any video. Is this the end of the world? Does making such a request ever attach a weak compulsion to review and request the same of any other video that might weakly overlap the criteria claimed in the first video? That's laughable. That's not how logic or anything in the world works.
The White House gets to use the power of the bully pulpit to make such a "request" and Al Qaeda storms a few embassies and murders diplomats to make their "request".
I'm sorry you're not as powerful as the president but that's just reality. If I don't like the leather iCal in OS X I get to say that in comments 100 people read. If John Gruber doesn't like it he gets a million Apple users and employees to listen to him. Jony Ive's opinion even more powerful. Things aren't equal.
