Maybe Kirk is trying to prevent Spock being too emotional in reacting to some action or threat against them, and he's doing this to make a point and 'snap Spock out of it' for a moment.
Thus Spock is not wigging out on his own volition, out of control, but he's being goaded into a fight -- and indeed baited to confront his human side and emotions. Being younger, I'd say Spock would have less experience handling that conflict 'in check' and would be a bit more volatile about it than he was in the TOS era.
Yeah, then Kirk's line 'Then why don't you stop me' could very well fit into such a scenario.
