I (26 F) have a little brother (20M) who had recently told me that he was transgender (FTM). I was very proud of him and support him, my little brother let's call him Victor has advised me that he felt like a guy since he was 16 years old but was too scared to tell anyone as he was scared that he would be judged. I told him that he didn't need to worry and that I would always love him no matter what. Now here's the thing our family are highly religious people and are also very traditional people, Victor wants to tell our parents as he no longer feels comfortable hearing our folks call him by his deadname anymore. I told him if that's what he wants to do then am happy to support him to do so, so after dinner Victor decided to ask our parents if we can talk which our parents agreed to. Victor then went on to tell our parents about him being transgender and things didn't go as plan, our mother was yelling and screaming at him and our father looked very disappointed. Our mother kept telling Victor that "it was just a phase" and "he needed to go and pray for forgiveness" and after a couple of minutes I had enough and told off my parents, my father started yelling at me and telling me that I shouldn't be supporting this and that his super disappointed in us both and my mother told me that if I keep supporting my brother that she will cut us both out of there lives. This honestly hurt my little brother and he ended up crying, I was also upset because while I live with boyfriend I still come and see my parents every weekend. I decided then that it was best for my little brother to stay with my boyfriend and I, which he agreed too. On the trip to my apartment he was very quiet and couldn't stop crying, it breaks my heart to see him like this. So Reddit I need to know did I do the right thing standing up for my little brother against our parents or was I the AH in this situation.
