Answer:
Well, the students in the Tinker v. Des Moines case wore armbands to protest the US involvement in the Vietnam War. Their act of speech was related to their opposition to US involvement in the war, and they were using armbands as an effective way to express their political opinion. In Hazelwood v. Kuhlmeier, the students of a school newspaper wanted to publish an article about the effects of divorce on students, to raise awareness and engage with their classmates on an important social issue. The students in these two cases were both expressing their views in different ways, but both acts were related to social issues that were going on.
