Core Idea
Coerced conversion treated Jewish difference as a problem to be erased. Yet the convert could remain suspect, because the accusation shifted from belief to sincerity, ancestry, or secret loyalty.
Main Pattern
Assimilation is demanded, then declared incomplete. The target is told to disappear as a Jew, but is still imagined as Jewish when blame is needed.
Historical Snapshot
Late medieval and early modern Iberia produced intense suspicion toward conversos, alongside inquisitorial scrutiny and purity-of-blood thinking.
Modern Echo
Modern demands for absolute disavowal can repeat this pattern when Jews are asked to prove loyalty in ways no other community must perform.
