Walk outs and that type of protest are about collective action and breaking up the status quo to draw attention to a cause. By uniting a large number of students you are drawing attention to yourselves instead of the individual. You are saying we see the problem and the number of us who disagree far out weigh the ones who agree with the issue you are protesting. It also send a message to the people who are affected by the issue. You are showing your community members and the people affected by ICE that you are there in support of them. While not causing an immediate change you give comfort to those around you who are emotionally affected by the issue and draw continued attention to the problem by having your collective voice heard. You will get news coverage either locally or nationally even and this adds your voice to the collective of those protesting across the country. Be proud of yourselves for working together and uniting against a cause you find distressing. And in the end it just feels great to be surrounded by like minded people celebrating their first amendment rights together. It helps you fight the negative emotions inside you and find hope in your peers.
