In the work place you can't use physical force nor can you use insults (verbal force). Some people are better at using verbal punches like insults, and can carve their opponent up. Others are better at physical confrontation but may suck at fighting with words. As long as nobody is hurt, I treat both forms of abuse as the same. A shove can hurt your feelings the same way an insult can hurt your feelings. Neither will leave a physical mark or cause any physical damage.
If I ride someone to the point I get them mad and then they react to me with a shove, I lit the fuse. I shoved him with words and he shoved me with his arms. This is cause and effect based on skill set. The dual standard seems to favor the verbal bully. One standard allows each person to be the bully, in whatever method they are good at, as long as there is no physical damage.
If you were in a bar being insulted by a lawyer, he is a professional talker and you will sustain emotional damage and may not be able to defend yourself with words. You may have to give him a swirly in the toilet, since he may be just a vulnerable at the physical level as you are at the verbal level. Since he is connected to the law, he will try to stack the deck in his favor so only verbal abuse is allowed but not called abuse.
I would guess your argument may have favored you orally. The other person could not defend himself and was sustaining emotional damage. He used his forte to level the field. The shove was an insult and hurt your feelings but is not considered violence anymore than an insult. It may have given him the last word, since your were no doubt more careful not to shove him back with an insult, out of fear of another physical insult. It all ended with nobody hurt physical but both hurt in spirit.
If a lawyer is carving up a witness to discredit him, the witness is not allowed to defend himself in a way he can even the score, even if the lawyers uses lies. I would change the law and allow the witness to put him in an arm bar and make him squeal. This makes the system honest. But since it is run by lawyers for lawyers the deck will be stacked so balance is not allowed.
