Still holding the old views, and not sorry about it. You use it for a person whose beliefs belong to an earlier time — a time that most people around them have moved on from — and who has refused to update. The classic partners are political and social labels: an unreconstructed Marxist, an unreconstructed Thatcherite, an unreconstructed sexist, an unreconstructed male chauvinist. "He is an unreconstructed socialist of the old school." The tone is nearly always disapproving, but it can be affectionate — a newspaper might call an old comedian an unreconstructed dinosaur and half-admire him for it. Two things sit underneath the word. First, it assumes there was a change everyone else went through, and this person did not. Second, it hints that the person could have changed and chose not to; it is stubbornness, not ignorance. That is why you would not call a child unreconstructed. The word comes out of a real historical moment. After the American Civil War came the period called Reconstruction, when the defeated Southern states were rebuilt and remade; an unreconstructed rebel was a Southerner who never accepted the new order. English kept the word and lent it to any old believer anywhere. This is a written, educated word — journalism, opinion columns, political talk. It is long, and speakers of English enjoy it a little. It is not a word you need in daily conversation.
