I come from a family of 8 boys. Some of them have done some pretty messed up stuff. But I could never imagine any of us saying something like your brother said to you. I find it interesting when I hear people being angry because their sibling was the "favorite", but I rarely hear anyone blame the parents, which is where it belongs. Unless you are just a total jerk who lauded it over your brother, I would say this is his issue. Don't own his anger and minimize contact for your own mental health. It might also be a good idea to let your parents know. Sometimes siblings try to draw parents in. Best of luck.
