Reasons I Don't Live In California, Part 745

I know public school administrators have a tough job.  But how stupid do you have to be to tell students that they can't wear t-shirts that feature the American flag because it's Cinco de Mayo?  Apparently, the American flag is incendiary on Cinco de Mayo.  It would make more sense if the French flag was a problem... speaking of which, why is it important to celebrate a victory over the French army?  The Germans would need to take a holiday once a week if they tried to celebrate every win over the French.  And don't get me started on the idiotic suggestion that the students turn their shirts inside out.
