I think I'm going to estrange my older brother.
Why do you want to estrange your brother?
He always acts like he belongs to a higher class and I can't stand this mentality.
It's generally safest to distance yourself from family members who cause you verbal abuse and harm. Remaining in a relationship with a toxic person is potentially harmful to your emotional and physical health and relationships.
I don't give a damn about you or anyone else.
Sorry, but there's no need for hostility. I'm just saying that you shouldn't let toxic people be in your life.
