what would you do to someone who verbally abuses your mom real bad??when they have neither right nor a reason to?

why?

Your mother would let it happen for the sake of protecting you interfering in first person will defeat that purpose ask someone else for help outside

If you can help her get away from it with the police and law but not in first person where your put in danger

@ErinFrisk: what if there is none n ur mom is too weak to just fight back?

Then like I said first person is no way to go I'd know that for a fact. Find someone to intervene on your behalf and stop what's going on
