the first problem is your link is to Fauwks 'News' (using news very lightly). Fauwks has made up stories to make minorities look weak and easily offended before, and often make it so the poor white man is being abused by the minorities. So until someone can provide a newspaper headline that isn't owned by Rupert Murdoch, i won't believe the story.
however, the article was kind enough to say what newspaper did write an article first. here is a link to it: http://www.startribune.com/local/126739938.html
Now, when you google "The Minneapolis Star Tribune wigger day" the first link is to Fauwks, the second to that link, and the third here, to this very thread. And i don't know about you other Americans from public schools, but typically homecoming takes place in late September to mid October, depending on the schedule of the football games. WHY then was this only NOW covered by the news? something like this in Ohio would get news for the notice that wiggers even exist. a student SUING a school? that would probably be a decision made far before an entire year had passed.
The whole article seems fishy at best to me.
