Yeah - I’ve had that as well. I am a lawyer, and tend to choose my words precisely, focussing on the word choice rather than the tone of delivery. I’ve often thought I was just communicating innocuously but directly and clearly with someone - possibly during a discussion or even a disagreement, to hear after that I was being intimidating. Often from women.
I imagine it is SOMETIMES the case that I should be more aware of my entire presentation, but I also suspect that at least occasionally the person calling intimidation is passive-aggressively trying to excuse their own wrong-doing. I’ve had incidents where someone did something clearly wrong (by the standards of where the action occurred) - and they know or should have known that they were wrong. My response was essentially, “Cut it out.” And the other person chooses to shift the focus from their wrong-doing which precipitated my response - to the appropriateness of my response.
