Katara wants to find her mother's killer and Aang imposes his beliefs on her and dictating how she should act on her feelings rather than letting her make that decision herself and making it look like she's evil for wanting closure and compared her to Jet of all people. It's okay because Katara finds out he's right all along.

Aang can't go into the avatar state without losing control of his pent up anger that endangers everyone around him but it's okay, Katara will pull him out of it while pacifying him like a child.

Aang makes a selfish decision, diminishes the same trauma Katara has of losing their culture, gets everyone killed because he trusted a random guy more than his wife but it's okay because Katara can bring everyone back and forgive him enough to still stay with him.

Aang wants to rebuild his culture and neglects his other non-airbender children while he travels the world with his favourite child but it's okay because Katara is there to be the parent that stays and turn a blind eye on how he treats his other children.

Katara can leave her homeland and not rebuild her people's waterbending culture and stay in the republic city to be known as the wife of the avatar and take care of the kids and not be celebrated for her contribution to ending the war as a strong warrior and be known as a healer and not have a statue and only return to the Southern Watertribe after her husband passed away like she was locked up in a cage.

Katara, the most out-spoken character in the GAang, becoming submissive and quiet to appease her partner, holding her tongue as to not hurt her boyfriend/husband's feelings and always prioritizing his feelings over her own.

Katara, who deeply values her culture, heritage and home, choosing to reside far-away from her family and friends, just so her husband can be closer to Republic City.

Katara, who taught the Avatar, who mastered water-bending in less than a year, who helped defeat Azula and ended the one-hundred year war... Not being honored with one statue, being reduced to the Avatar's wife and mother of his children, becoming known as a healer when she was one of the best benders of her time.

You see this? This here? This pissed me right off. Where does he get off? They've been travelling around the world to help him master all the elements and the Avatar State -specifically to end the war, mind you- and and this is the first time he's thought about HOW he's going to defeat Ozai? And he's shouting at Katara, like it's her fault he waited until the night before the assignment was due to think about how he was going to do it?
