I do not, in any way, disagree with holding Gaggle accountable for this.

But can we at least talk about also holding the school accountable for the absolutely insane response?

You talk about not selling to schools that have "zero tolerance" policies as if those are an immutable fact of nature that can never be changed, but they are a human thing that has very obvious negative effects. There is no reason we actually have to have "zero tolerance" policies that traumatize children who genuinely did nothing wrong.

"Zero tolerance" for bringing deadly weapons to school, I can understand. So long as what's being checked for is actual deadly weapons, and not just "anything vaguely gun-shaped", or "anything that one could in theory use as a deadly weapon" (I mean, that would include things like "pens" and "textbooks", so...).

"Zero tolerance" for particular kinds of language is much less acceptable. And I say this as someone who is fully in favor of eliminating things like hate speech or threats of violence—you don't do it by coming down like the wrath of God on children for a single instance of such speech, whether it was actually hate speech or not. They are in school; that's the perfect place to be teaching them a) why such speech is not OK, b) who it hurts, and c) how to express themselves without it, rather than just treating them like terrorists.
