It's against school policy to support victims of the [in]justice system. Look at this blue shirt. Are you threatened?
The students wore the shirts to not to piss people off, but to "make a statement." Making statements apparently is not a good thing to do at school in some parts of Louisiana.

It s*cks that people are judged by their race, religion, national origin, sexual orientation,size, gender, and even for being disabled in any way....
And that is how Republican America wants to keep it.
White Males in, everyone else on the fringes..
The only way it will change is if people wake up and realize that freedom of speech and freedom of expression are being curtailed by BUSH and his GOP cronies.
