This bell ringer can be used to introduce students to critical thinking around violence vs. nonviolence and freedom of speech. It uses the punching of white nationalist Richard Spencer during the 2016 presidential inauguration to explore issues surrounding the First Amendment and violence vs. nonviolence.
Teachers may opt to show the actual video of Spencer being punched. Several clips can be found on YouTube. It is up to the teacher's discretion whether or not to show this. Since it does contain violence, the teacher may wish to contextualize it by explaining that it is no more violent than any other period of American history.
The bell ringer will get students writing and thinking critically about current events, while examining their own beliefs when it comes to freedom of speech.
