In fact, the continuous criticism of Rachael tends to give rise to "the underdog effect" in her favor. The "underdog effect" occurs when someone is so continuously criticized that it seems like severe piling on, if not bashing.
That causes people who get tired of the piling on to say a nice thing every once in a while about the skater, just for variety, even though she/he is not their favorite. And that emboldens people for whom he/she is a favorite to have the guts to brave public criticism for their "bad taste" and to post to that effect.
If this escalates, other people actually become fond of the underdog, and fond of their championing of the underdog, and start searching for positive things to like about the underdog. Some will even become uberfans of the underdog.
I suspect this is not your intention, but it is often how things work.
Someone gets it!
But it's not just Flatt; you can put any other skater's name and the statement would still be valid. I'd even argue that it works in reverse, too: those who continually wax poetic about a particular skater. People who are annoyed are going to begin to find faults in said skater and point them out...and then for some, it can get extreme.
One thing though: I do have to disagree with the "uberfan" part- for example, I don't know of anyone who became a staunch Cohenhead or Slutskaya fanatic due to the actions of Kwaniacs. However, I do think that it enables those who are ALREADY uberfans of the rival skater to take their uberfandom to a whole new level.
