The majority has voted. She has committed Thought-Crime... er, hair-crime, anyway.
Her parents (like the rest of us) pay $7,000 per-child, per-year to the Gubmint Schools; but in the Gubmint Schools, your money is not your own.
Alternatively, if her parents are not of the opinion that dread-locks are inherently Eeeeeevil, a "crime against God" (according to so many Freepers, apparently), we could just give her Parents back their $7,000 bucks and let them pick their own School.
But if we did that for everyone, we'd have to abolish the Government Schools.
Separation of School and State.
What a travesty that would be.
