Students Should have a voice

The reason im am startind this petition is beacause on March 20th i was involved in a walk out at my school. I had a idea to walk one lap around my school with the 30 to 40 students who walked out with me. When we were walking and saying "Make peace, Not war" (at lunch) the teachers starting yelling at us and told us to stop. In my school The students have no voice we get in trouble for saying what we think. I would like to get as many people who support me to sign. Yes i maybe 16 but i have a voice and im TIRED of adults saying that i dont and that i dont know what im talking about.So if you agree then thank you.
