Perhaps.
I know there are a lot of people who have Jewish ancestry. And it is nice when they are proud of it, like David Beckham. Others learn they have Jewish ancestry and become misguided about it. But those like this man Maduro who claim to have Jewish ancestry, it just does not matter. When a Jewish man has non-Jewish children, it is as if they are not his children. So, having this ancestry has 0 meaning.
