Cardinal Lustiger was not brainwashed. he was not kidnapped. He was not coerced into Catholicism. he accepted it during Holy Week 1940. He was baptised and later after the war ordained a preist. His father was present at his ordination. His mother, betrayed by a neighbour was gassed at Aushwitz. You assume that any sane jew could never possivble choose of their own free will to become a Catholic and yet still feel they have a strong Jewish identity. But that is more your problem to deal with than those converts who have found a resolution to that apparent contradiction.
