When you have to use the original meme to get a point across
Walk out. There is no such thing as a permanent record, but there is such a thing as ‘the entire administration gets sued and fired’.
I want to add again that schools are allowed to punish you for missing class to protest, but it has to be the standard punishment for missing class (as though you were missing for any other reason). If they would not normally suspend you for 3 days for missing class, then they cannot do it for this. It is a violation of your first amendment rights to punish you more harshly for protesting than for any other reason for an absence from class. [source – ACLU]
If your school is threatening you with a punishment that is beyond what would normally be given for an unexcused class absence, you should contact your local ACLU chapter. You should be able to find the standard disciplinary actions for excused and unexcused absences in your student handbook; if the punishment for protesting is different from the punishment listed in the handbook, then you need to contact that ACLU.
