comparing it American criminal law. Any person who commits a felony in the U.S. automatically has revoked certain rights and priviliges. But it does not take away the fact that he remains a U.S. citizen.

So going back to your questions:
Since children from the Anusá maternal line remain Israelites ad perpeteum, they are still Israelites [alt. Jews] according to Jewish Law. So the descendants of the Spanish Anusim are Jews, eventhough most be practicing Catholics. The Anusim children belief system or "religion" does not change the fact that they are still Israelites.

As far as speech, word usage does not determine nationality. Or is it that using the words Chocolate (from nhtl. Xocolatl) or the the word Tomato (from nhtl. Xitomatl) would make you Mexican?

If you can help me to clarify this succintly on the article, it would be helpful.
