I'm mad at my partner for getting mad at my parents
what are you going to do about it?
I'm going to confront them about it.
I understand your anger, it's justifiable. Your partner is supposed to get along with your parents as well.
I am mad at my parents too. I want to beat my parents.
I can see why you would be upset with your parents and your partner. It is hard to see the people closest to us disagree and fight. You should try talking to them both so that they can settle things.
