Does participating in a school walkout affect someone’s appointment? Please leave out personal political opinions
Edit: I am not participating but I think it is an important topic to address
From a purely Constitutional standpoint, it is unconstitutional for schools - public or private - to ban or curtail the exercise of protest or free speech in school (Tinker vs. Des Moines Independent Community School District 1969). Private schools usually enroll students at-will, so many have no due process to dis-enroll students. In other words, some could boot you with or without cause. You'd have to check with your school about that. Either way, that SCOTUS ruling applies to public and private schools.
From the standpoint of the full and free exercise of Constitutionally-guaranteed rights, I am more than a little disappointed in the advice
to play it safe or hold back (e.g. this is not
a personal attack on those individuals). Here is one young person willing to exercise their Constitutional rights to speak and assemble, who is dedicated to at least five years as an officer sworn to uphold and defend the Constitution against all enemies, foreign and domestic. It seems to me that apathy is one of its most insidious enemies. Defending the Constitution is never safe or convenient, but it is absolutely necessary.
, if you are worried about the effect on a SA or ROTC application, it seems to me you could make that a theme of an essay.
