Again you are missing the point. You keep looking at the act of "arguing" and missing the bigger picture/motivation, (which is very woman-like btw).
A woman who feels like she can challenge you all the time is not feminine. A discussion is one thing and yes even fighting is too. But a woman who is combative and argumentative is not feminine. And logically if you are not feminine then by default you are behaving in a masculine manner.
I also think you have a misunderstanding and think that when a woman is said to display masculine energy that means she is behaving exactly how men behave and that is not necessarily true. A masculine woman is not the same thing as a masculine man.
Yea and I guess making passive aggressive insults in the middle of trying to appear diplomatic is masculine
