The issue is that the kid was being punished for the content on his t-shirt. If the school had a dress code that forbade all t-shirts, which public schools can and some do have, there would be no issue. But the argument is that the kid wouldn't have gotten in trouble if the shirt had had pictures of sunshine and lollipops; he got in trouble for expressing an offensive message, and government agents (public school employees) are bound by the Constitution not to selectively discriminate for or against any given message, even offensive ones. See the difference between your list of rules (which penalize behavior) and this case (which was an attempt to penalize content)?
All of which has nothing to do with the most important issue in this story, that being that this poor kid was raised by moonbats who dumped enough nonsense down this kid's throat that by age 12 he was permitted (if not forced) to wear clothing with stupid and offensive messages in public because those messages represented the parents' geriatric-hippie worldview.
Red herring. The issue is the depiction of illegal drugs and drug paraphenalia which schools have a right to ban. Could he have worn a t-shirt with an image of Monica getting down on Clinton? I say no, because the content being forbidden is not the political content, but the sexual content. In this case it is the drugs.
As I understand it the school has a policy that forbids the depiction of illegal drugs and drug paraphernalia.
Clearly, that is not the case. If it were, there would have been no lawsuit and no thread.
However, the have nothing to do with the legal issue in this case
The point was.....30 years ago, there would have been NO legal issue and NO case.
(and I have no idea what any of it has to do with abortion).
Nothing to do with abortion other than when our judicial tyrants granted abortion "rights" the country as a whole began to go downhill rapidly. Children that were granted the privilege of birth suddenly were given "rights" that up to then adults didn't have. The anti-war, free-love hippies of the late 60's/early 70's were behind the degeneration of our society.
Many of them are the leaders behind the anti-war, anarchist movement of today.
