I knew some families with that behavior. They are rare, but extremely hurtful. Look into trauma therapy (and ask a therapist what makes them qualified for that, instead of taking their word). You may have developed some hidden coping mechanisms just to survive, and a (good) therapist can help you determine if those mechanisms help or hurt you.
Your brother’s behavior seems extremely uncommon, to say the least. I can’t imagine that behavior being tolerated in a (functional) work place.
I wish you the best.
