^^ I agree with everything Orobas mentioned.
But really, no matter what, I think cutting out your sibling is not the greatest idea. Just try to give each other some time and space and try to re-patch things when both of you are ready.
Since I'm an only child, I've always hope that I had a sibling. I also thought having another person who share most of your family history is valuable even though they may not share the same perspective on certain issues. I think it helps you to learn from a different perspective by sharing and learning from a sibling if both manage to respect each other.
