The US Supreme Court found marriage of Constitutional proportions and extended the right of marriage to same-sex couples. This broad sweeping Constitutional rights opinion will have profound effects on many aspects of our society, not just the right to marry. It will apply to right of adoption, inheritance, death benefits, divorce, and maybe other ways we haven’t even thought of yet.
