Why would any child or parent object to fingerprinting?
Coercion and regimentation in government schools is just the *real world*, to wit:
Riding buses of a kind that nobody else rides except in prison or at boot camp, painted a special DOT color that other vehicles are not allowed to use, that travel under special traffic rules that nobody else is allowed to use.
Eating food provided by the government, served in a facility with famously odd personnel, none of which would be patronized if offered to people as a free choice.
Forced to endure unwanted company that inflicts physical assaults and social harassment that would be criminal or tortious if acted by adults.
Required to submit to government employees who are 100 percent unionized and paid twice what they're worth in the free market, who work 3/4 of each day for 3/4 of the year. (For those of you who learned public school math, that's 3/4 x 3/4 = 9/16, or about a half time job for double a full time annual wage.)
The real world?
