@msolga,
The "fan" part has nothing to do with Facebook, it has to do with exuberance and silliness and not taking this all too seriously.
I haven't seen "my country right or wrong" sentiments expressed by Gracie -- just a lot of goofiness and exuberance aided and abetted by a whole lot of internet memes, that was tempered nicely by her acknowledgement of snood's post.
I don't think she was making a goose of herself, and find that accusation to be a misreading of her tone and intent.
Meanwhile, I do see how you can both say no to whether you love Australia "warts and all," but then also say that you love Australia. I feel the same way about America -- I love it, but I don't love its warts. And of course it has some.
