In my experience when you respond with like the escalate like mad, probably due to pp point about backing down to a woman being simply not possible.
I jabs had men scream in my face, spit at me, follow me shouting, throw stuff at me, yell at me to "take it outside" ie have a physical fight, been pushed, pulled, had a pint tipped over my head...
I was punched in the face once but there was no previous interaction he just walked up and punched me in the face.
I have also had plenty of young men deliberately boot footballs at me, which I mentioned before a poster came on to point out that would never happen 
.
Just shows how off the mark men's risk assessments are, they literally cannot put themselves in our shoes and simply do not listen.
Woman know too well the anger some men show when women don't behave how they address supposed. Obviously, men have not experienced this. Add the ever present undercurrent of possibility of sexual assault, and advising a woman to stand het ground and give some verbal back, to a group of young men in a park, yeah great advice.
The proper advice surely is to leave , get away. I have certainly not advised my daughter's to get arsey if they feel threatened by a man or men, I have said just get away.
