Frankly, this article is the "same old, same old" he's accusing figure skating of being. It's shoddily written, doesn't offer anything new (and thus, he doesn't even bother to argue anything since it's so "self-evident"), and seemingly written in complete rage without any kind of use of...

Just because he has a few correct points doesn't mean this type of journalism should be encouraged (other sports having shoddy journalism isn't an excuse--that's like saying "every country cheats so why not us? ).
