AITA for saying my FIL doesn’t know how to parent?

So all of this blew up yesterday and I don’t know if I went too far or not. My husband (23m) had just dropped me (25f) off at work and was going to visit his parents’ house. When he pulled into their driveway my SIL (19F) comes outside and start screaming that he can’t park there. My SIL has a tendency to be rude and disrespectful especially to my husband/her brother. Yes ik she’s 19 but it has been that way for years. My husband is the type of person to put up with a lot but like most people can only handle so much. He told her to quit being a bitch. Well she goes inside to cry wolf to my FIL (68m) who starts berating my husband. Then my husband calls me at work and tells me the whole situation about to have a panic attack. I was so fed up with everything that I told him to go inside to talk to his dad where I said that this had gone on long enough. My FIL started yelling at me about the whole thing and I said “ *husband’s name* has dealt with this verbal abuse all his life and he calls her a bitch and he’s the villain?” My FIL proceeds to hang up the phone on me. When I called back he said I was being disrespectful so he hung up. I then said “ no wonder *SIL’s name* is the way she is her dad is a childish person who hangs up the phone when he hears something he doesn’t like and doesn’t know how to parent.” I said you say good bye before you hang up so I said good bye and hung up after that. I’m starting to wonder if I took it too far. I am just tired of my husband getting verbally and mentally beaten up by his family. I love him and will protect my family always. So Reddit, AITA?
