Am I wrong for not physically beating up my son for mouthing off to his mom when he is in a bad mood?

My ex always expected me to beat up our son when he got mouthy to her when he was in a a bad mood , I would verbally get mad at my son and tell him not to talk to his Mon that way and to apologize , but I had no intentions of beating him up over it , unless he got completely out of line and out of control , But after I yelled at him , he would get quiet and walk away to take a breather. But my ex then started attacking me verbally , saying I am not a real man because a real man would physically attack his son for speaking to his Mom that way. Me personally didn’t agree with her, because beating someone up doesn’t solve anything plus I was raised by an alcoholic abusive father that would beat me and my brothers’ up and the only thing that it taught me , was that my Dad was a complete asshole and I lost all respect for him for it. I chose not to be that way with my kids’ whatsoever. So am I wrong for not physically beating up my son for being in a bad mood and being rude to his mom?
