Does your ideology radically change over your life? Why would theirs? They judge with their own biases, and are often out of touch with public sentiment. They're just people, and in case of at least one, a rapist with powerful friends.
A bigger court elected by the people could help solve that problem. Not lifetime appointments with zero accountability. The Supremes are just another fascist and anti democratic institution, like the electoral college or the party apparatuses.
