l2g, I don't think you lie.  But I think that you are not Donald Trump.  We must all understand the limits of our knowledge.  Trump is not a woman.  The concerns about dominance and especially discomfort that you mention are not typically perceived by males.  When you say he was overpowering on purpose, I can't put trust in the conclusion because there is no way you can know what his intent was.  Setting aside politics for a moment and just viewing the two people on the stage, I interpret Trump's mannerisms and movements as unpremeditated release of tension.  Not being a lifelong politician, he has not been trained to stay in one spot and smile.  I myself in making public presentations tend to wonder about the stage.  For me, breaking away from the sitting with a smile relieves tension.

So truth be told, we do not know whether Trump intended to "overpower" her or whether Clinton felt intimidated at all.  Projecting our own feelings leads to incorrect perceptions.
