Gentle-aggressive 

A gentle-aggressive person is an unremarkable or medium sized person that is not small enough to have full blown Napoleon's syndrome (like Derek Chauvin) but not large enough to be a gentle giant, so they might or might not become aggressive with a larger person, and usually be gentle with little people and midgets, but might get mixed up and end up being aggressive to the little people and midgets every now and then, and become gentler with the larger people, the giants.

The gentle-aggressive guy wasn't passive-aggressive, he was usually gentle with the midgets and he was nasty and aggressive with people that were too tall, but then sometimes he would be nasty and aggressive with the midgets thinking he might have done the wrong thing, and he would be gentle with the giants instead, all of which seemed like a human and inhuman thing to do at the same time.
