OP hasn’t been back since the 19th.
Not all “activism” is disruptive. There are many kids campaigning for clean water, various rights, advocating in their communities, working directly on causes or with the needy, implementing change. They’re putting their efforts where their mouths are, so to say. That’s good. As an educator poster recently said somewhere, these can be the kids who regularly step up.
Many college kids advocate through positive actions and you see that in their college activities or work. That can be a fine spirit to add to a class. Many colleges will look for that. Those kids aren’t threats. Their heads are screwed on very right.
But just arguing with the hs admin, while it may be well-intended, doesn’t tell us where her soul is. It neither says she’s a disruptive sort, nor that she’s got perspective outside the hs.
We’d need to know more.
