The Tinker v. Des Moines Supreme Court case concerned two students who wore black armbands to school to protest the Vietnam War. The school district suspended the students, possibly violating their right to free speech. Which best summarizes the dissenting opinion?

A. The Des Moines Supreme Court had already ruled in favor of the school to suspend the students.
B. It was proven that other students were allowed to wear controversial symbols, so their suspension was unconstitutional.
C. Because the armbands protested the Vietnam War, the lawsuit was actually a question of Second Amendment rights.
D. Schools have reserved the right to limit expression in past cases and the armbands were, indeed, disruptive.
