Excellent point.
That is the critical difference between conservatives and libertarians.
Libertarians want no restrictions and code of ethics.
Conservatives want as much freedom as possible with voluntary restraint so that some governing authority doesn’t control our behavior for us.
So, you think conservatives want a government powerful enough to control our behavior if we don't act properly? Interesting.
Conservatives want as much freedom as possible with voluntary restraint so that some governing authority doesnt control our behavior for us.
You don't understand libertarian philosophy at all (big or small L). Libertarians want people to determine ethics and morality based on their own faith, education, and family values. They don't believe that "some governing authority" has the inherent right to control our behavior except when it impinges upon another person's rights. This belief is consistent with that of the Founders. For those of us who believe in God, the source of our code of ethics is our faith. It certainly isn't some bureaucrat in Washington.
In this particular instance, libertarian philosophy strongly supports the right of free choice in association, and the right of individuals, businesses, and organizations to set the conditions under which they engage in transactions. There is no basis whatsoever under libertarian philosophy for the girl to argue about the rejection of her picture - it doesn't meet the requirements set by the yearbook committee, and they are therefore fully within their rights to reject it. Of course if she wants to publish her own competing yearbook with whatever kind of pictures she wants to put in it she is welcome to do so.
The existence of a compulsory government school is what leads to the legal challenge that the student may make. If she didn't attend a government school she would have no basis whatsoever to bring any legal claim about the yearbook policies.
