Today, I caught my father peeping through a keyhole into my brother's (21 y/o) room (He is paranoid and thinks my bro is playing games). I said (almost shouted) "what are you doing?". He told me to shut the fuck up and walked away, I told my brother. My father started raging again, and told me it's none of my business even though he's disturbing my adult brother's privacy. I told him it is my business and it's like talking bad about a person, you shouldn't be surprised if someone tells them. He pulled the 'you are young and have no idea and should share my values completely because you can't think with your own brain'-card, which makes him a disgusting person, and told me not to do that again. Was I right or wrong?
