If I were asked to decide if a certain incident that I didn’t witness or have up close information about was “bullying” rsther than just icky behavior them I would need to see extensive documentation from all parties. Or a very clear hypothetical situation. And frankly I’d be disinclined to put the effort in unless I was in some official tribunal or union grievance committee or something.
So I simply cannot respond meaningfully to a question like, is it bullying to hit a dislike tab? By an individual no. As an organized attack by a big group, trying to drive down some one’s Google rating? Absolutely it is an attack and harassment.
Is it bullying to refuse to talk to someone? In most cases no. In some specific school situations though that could very well be part of a campaign of exclusion against a child.
In other words it is not the single specific action that is defined as bullying but the intent and the clear pattern of action.
Little girls can bully with the subtlest cues that no teacher or parent can even see let alone control.
On the other hand men can be incredibly aggressive to each other physically and intellectually, call each other names in Parliament, etc and still actually be on pretty good terms with each other.
It is not the act per se but the intent and the context.
So just dropping rhetorical questions like is it bullying if??? doesn’t add to the discussion much because we can’t say one way or the other.
