This girl blew up on me over INSIDE OUT

This girl was talking to me asking who my favorite character from inside out is. I said sadness and I didn't really like Joy because of her toxic positivity. She got so upset because I get other girls said they didn't like Joy either. She said Joy isn't toxic. She wanted Riley to be happy. I was just explaining that, while thats true, she was a bit of a control freak and by not allowing Riley to properly feel sadness, she accidentally broke her brain. And she starts going off on me saying how I'm wrong and it's incorrect. She said the movie is about how to be happy. I stated my opinion which was I don't think it was about how to be happy. I think its about it being okay to be sad and how its important to feel all your emotions and you can't really feel Joy if you haven't felt sadness. She again said my opinion is wrong and said something must be mentally wrong with me to like sadness over Joy and I must be so depressing and all of this nonsense.... Like... Its a movie... Sis its not that serious...
