This really bugs me. How did this case make it all the way to the Supreme Court? If you're in a public high school, and you make a banner speaking out against Christianity, why would you muddy the message by including a drug reference? Maybe he'd have actually won his case if it said 'Military Occupations 4 Jesus.' Or he could've just hung a banner of this:
There! No sending a mixed message, because the last time I checked, Snickers were legal for high school students to consume. However, please let me know if times have changed since the early 90's.
Also, how did Kenneth Starr become involved in this case? Was the kid wearing a blue dress? Did he mention a blow job? Held up The Shocker?
