You should reevaluate if you think disagreement is bullying. Disagreement feels like bullying because being wrong is one of the worst things that could happen to our psyche. Because people on the “wrong side” were often attacked and killed throughout history. But in a more enlightened culture, that we’re trying to rationally work towards, being wrong and people disagreeing should and needs to be fine. It still feels unpleasant of course, but disagreement and hostile behavior needs to be distinguished.
