my parents kicked my brother out for being transgendered

My parents are old school. My brother is transgendered and feels he is a women. He is not a nice person and is disrespectful and selfish. However my parents kicked him out because they aren't comfortable with his lifestyle. He's 21 and almost done college. He hasn't spoken to me or my parents since moving out. Do you agree with all this? I feel like my parents should be comfortable in their own home and he did nothing to help out. He's not a nice person but I still feel bad for him....
