You need to look no further than your manager and other senior leaders. Everyone will take their cues for behavior from those people. If they are confrontational, the people who work for them will be, if they aren't that way (and they call out as bad behavior such things) then the behavior won't be present.

Personally, I don't believe we are confrontational in general, but we respond badly to because-I-say-so situations.
