Saying The Pledge of Alligence is "Supposed" to be a Choice

I believe it's total BS that our schools are forcing students to say the Pledge of Alligence. It is "supposed" to be a choice of the students whether or not they want to say it. There are students in school who are Satanists, Jehovah Witnesses, and Atheists, and chances are they're not going to want to stand and say the Pledge. The government has to start remembering that everyone has different beliefs and not all people believe in god. Technically, by making the students say the Pledge, the government is infringing on one of our rights, Freedom of Religion, because of the words "....One nation, Under God...". Even without that, it should still be a choice of the students. I remember a student getting in trouble for not standing for the Pledge. If you also think what I'm saying makes sense, please sign my petition because if possible, I am going to show this to the government.
